>hydraulic disk brakes would have prevented this editionResources:https://www.sheldonbrown.com/https://www.parktool.com/en-us/blog/repair-helphttps://www.youtube.com/@RJTheBikeGuy/videoshttps://www.youtube.com/@durianridersNeutral Support News on YoutubePrevious thread >>2064038
>>2065460>I can access a place that's basically a charity(sort of) bike repair group that's run out of a small brick warehouse unitAnd by the looks of it, they've closed down in the last month and a half. The last bike shop I even know of that isn't that one incredibly shitty chain store is now even further away and even harder to get to by public transportation. We're hitting levels of JUST that shouldn't even be possible.
>>2065539turns out that there's no way to run a business when your aspiring customers regard replacing a ruined $20 wheel with a new $50 wheel as a hardship
>>2065541>spokes loosen>wheel ruinednigga wtf
Who is responsible for making both 200mm rotors and 203mm rotors? Why is every industry fucked with constant bullshit where you have to have special parts, there's nothing truly standard. Just a bunch of proprietary shit. 130mm skewers, 135mm skewers, different bell ends. Press fit BB, different size BBs with slight differencesIt's all too much. I'm just gonna pay the extra $, fix my shit and ride my bike. Sorry not sorry
>>2065541That same wheel cost me 50 back in September.
>>2065530There is this I don't get, I have 622x32c tires with mechanical disk brakes and the rear wheel skid all the time, so I use the front one as gently as possible, that said, isnt hydraulic disk brakes overkill? at least for thin tires
>>2065555well for one thing rims with a braking surface are objectively worse and wear out faster. for another hydraulics have much better modulation.
622mm rotors > 160mm rotors
>>2065541Oy vey! He should be buying a whole new bike!
>>2065555>, isnt hydraulic disk brakes overkillyes, but you'll never convince anyone in that cult.
>>2065573you don't ride anything but perfectly flat and paved surfaces I see
>>2065574no, I ride all kinds of shit
I like how easy hydro brakes are to use. I have a hydraulic brake bike and a rim brakes bikeDiscs for dirtRim for roadSimple as
>>2065579it's almost like some sort of 3rd party would like to provoke divisiveness... couldn't be any of the many global south actors of course
>>2065555>isnt hydraulic disk brakes overkillno they're awesome, even for brake feel, ease and modulation alone.also always use both brakes.>>2065559yeah, until said big rotor gets covered in snow/ice/dirt/mud because of it's proximity to the ground
>>2065605>yeah, until said big rotor gets covered in snow/ice/dirt/mud because of it's proximity to the groundI run rim brakes and because the dogshit stopgap wheel I slotted in is painted, it stutters wildly and even when it doesnt has severe drop in braking performance when it's wet. my shitty 10$ chink disc brakes aren't good and NEVER offer good braking performance, but have NEVER dropped below that level of "barely adequate to keep me from getting killed" no matter how much snow and salt gets in there
Rim brakes would be fine if they didn’t destroy your wheels. Wheel manufacturers need to make replaceable brake strips that can be attached to the wheels. Until then I’m using discs.
>>2065613>Rim brakes would be fine if they didn’t destroy your wheels.Explain how rubber bushings squeezed by hand can "destroy" a steel wheel?
>>2065616Have you ever rode a bicycle
>>2065616nta but wearing down rims to the point they can fail isn't uncommon at all, it just takes a while. its why you should clean the rim track very often and make sure theres no small debris or dirt embedded in the pads themselves
>>2065616is this bait, also most rims are aluminum alloy
I have a carbon bike, an accident caused some paint to chip on my frame, I color matched the paint from the manufacturer but I need to clear coat it after too. What should I clear coat my frame with? Just an acrylic clear coat? What do they spray on most bike frames to protect the paint?
>>2065620>>2065619actually that asshole, but i've gone through a lot of parts lately; way more than I used to before getting back into cycling.>>2065619>clean the rim track very often I did this, and it worked until I installed a stopgap front wheel off a bike that has painted rims. actually surprisingly, water and snow have nowhere to go so the rim brakes with cheap brake shoes do very poorly in wet and/or freezing conditions. I am unwilling to trade out the wheel because i am a poorfag.>>2065620fair, every wheel in my possession is probably aluminum but still. the >IMPLICATION is that the metal would somehow warp or otherwise fail, which is unrealistic under clamping with rubber brake shoes. I have observed this winter that heat is important but the brakes do not generate enough heat to do any damage to the rim; the rim is not reaching even 100. but the shoes do need to at least be above around -5C to work at all
>>2065618my wheels do not look like this because the factory coated them in enamel paint like some kind of asshole and are mostly smooth under that. or at least my front doesn't, barring some parts where the paint wore off a nd now it's smooth metal. a proper wheel should have channels milled right in to both allow shoddy brakes somewhere to flex into as well as allowing brake shoes at all to bleed off water and ice
>>2065622its not that brakes put enough force on the rim to do damage its that over time it wears down. i saw a post a month ago about a guy who went into a shop for 5 mins, came out and his rim was a taco. in the pics you could see the brake track was fully worn through. if you have rim brakes it should be part of inspecting your bike for safety
>>2065624>rubber brake shoes never wear out>an aluminum wheel, though, oy vey, you need a new whole wheel every season!!!
>>2065625I’m not making my nice wheels a disposable item just to be a hipster fag.
I've been riding rim brakes my whole life and never wore out a rim, but I haven't been riding the same bike the whole time. anon who actually has worn through rims posted this
>>2065629most rims you'll find worn through are neglected more than used so its the brake pad being totally worn down and scoring the metal causing it to wear much faster
Ive worn a set of rims before, with fairly good maintenance too. but it wont just happen overnight.OTOH ive seen a boatload of rims bowed out or crack in da shop
>>2065634>rims bowed out or crack in da shopyou mean because the braking surface was worn down and you inflated the tire and the pressure cracked it? or something else?
>>2065660Yes, worn down to nothing, about 5 cases over 5 years id say.Never on inflation though, although we had a customer experience that while trying to inflate her tire though
>>2065663do you attribute the wear to riders who put down over 60k miles like the screenshot guy, or were these cases of abuse/worn pads? I assume by the type of bikes and clients it would be obvious but you tell me
>>2065666brake pads worn down to metal and big chunks of metal embedded into the pads usually is what does the rims in, a concave wear pattern I have not observed usually, just thin,deep gauges
This looks so fucking stupid, will a larger and stronger magnet be enough to straighten the sensor in line with the fork? The manual says 5mm gap max with stock magnet which is fucking stupid.
>>2065699>The manual says 5mm gap maxI mean, you could move it further away, spin the wheel, and see if it still reads, manual be damned.but I think you're right about a stronger magnet. it certainly won't hurt anything to try it out.also, if you move the magnet more towards the hub, that'll put it further outboard and put the sensor down to meet it, it won't be angled as much. it looks like your sensor is halfway up the fork
>>2065700Yeah I tried that but it seems the manual is pretty much correct. It’s close to the hub already the pic just has a bad angle on it. Pain in the ass.
>>2065699Mount it on the other side where the disc isn't in the way.
>>2065704I’m retarded sometimes thanks anonymous.
>>2065713You're welcome. So am I anon, I went through the same thing until I realized and even then took like 3 years to bother moving it over.
>>2065621since no one answered, I just went with a rustoleum satin clear coat, perfectly matched my bike's current coat, dried fast and seems very water / sweat repellent.
>>2065746>carbonif you had a good enough accident to crack paint, are you sure you didn't damage any of the carbon itself structurally? if your lbs handles carbon repairs they can x-ray it
>>2065746i missed it, but paint failing is an excuse to repaint entirely, imo. shoulda got some rattle cans and tape to put a really wild design on it
Is there an Aliexpress full mudguard kit for 29” wheels? Proper touring style that goes right down to the chainstay at the back wheel and most of the way to the ground on the front. I couldn’t find any and I’m not paying $150+ to buy two pieces of plastic locally from the big bike shop Jew.
>>2065767No. 29" is non-standard and no one has ever made parts for it.
>>2065767I gotchu lil homie https://www.aliexpress.us/item/2251832692163628.html?there's 700c and 29, you didn't say if you had road or mtb but there's both, plus 26 and 24 in case anyone else is interested.this is a fantastic deal. I paid something like $60 for metal VOs long ago and they go for $100 now.it is weird that most of the other ali fenders are only partial coverage, since the PRC is the world champion cycle commuter country. or, it was until the 90s, at least.
>>2065768not him but almost all the 29 fenders on ali are not full coverage
>>2065769>$80 shippingNigger nigger nigger nigger>it is weird that most of the other ali fenders are only partial coverage, since the PRC is the world champion cycle commuter country. or, it was until the 90s, at leastDude right, even today shitloads of chinamen ride bicycles and they are almost all commuter bikes with full fender kit. Why doesn’t whatever factory that makes them sell them on Ali.>>2065768>29” is non standardIsn’t it the same as 700c which is on like, every modern bike? Why are bicycle wheel standards all fucked up? I think mine are technically 700c.
>>2065771700c is not the same as 29" you monkey fucking furfag nigger.
>>2065773Yes it is retard
>>2065792
>>2065773see, this is why nobody likes you.so, if you called him a monkey fucking furfag nigger because you thought he was wrong, but actually it was you who was wrong, then that would make YOU a monkey fucking furfag nigger, wouldn't it?
>>2065773lol, lmao
>>2065768>>2065773wow look at this fucking retard
>>2065771>$80 shippingwhoa, did not see that.I found the seller that has free shipping, they have all the sizes but on separate pages700chttps://www.aliexpress.us/item/3256807326233824.html?other sizeshttps://www.aliexpress.com/store/1103153377?spm=a2g0n.detail.0.0.1f38H1L9H1L9aV&shopId=1103153377&sellerId=2676890791&pagePath=shop-wireless-search.htm&sortType=best_matchso frustrating dealing with Ali's search, I already knew it was hot garbage, but this one was like pulling teeth
>>2065806>other sizesah, they don't list the whole search, but it's for the right store. you have to type "mudguard" into the bar, they don't use the word "fender"
do they have chinese clik valve clones on aliexpress yet?
>>2065767try googling "eurofender"italian brand of cheap fenders
>>2065845not him but I can't find eurofender in the US.>>2065767are you in the US?
Why doesn't anyone make 26" wheels or tires or even brakes anymore?
>>2065756It was just damage from me pulling my cycling shoes over the top tube of the frame when I first got the bike, I hit it hard a few times with the cleat and it caused the paint to chip, the carbon wasn't damaged at all and I did a bunch of tests to make sure.
>>2065887>it's just seasoning BRO
>>2065880There are plenty. Just not gay nerd bikes.
cant you just adjust your seat to give you effectively shorter cranks
>>2065890that would only make sense if the crank arms were aligned and not 180 opposed. like if you had to pedal your bike by jumping up and down like a retard. how funny would that be though.
>>2065890nope, changing the saddle height changes the distance between the saddle and the crank but the diameter of the crank rotation has its axis at the bottom bracket, that means the only way to change crank rotation diameter is to change crank lengths
>>2065845at my work we use eurofender on our rental bikes, they crack if you look at them wrong
>>2065889bmx is lame af if you're not a kid>>2065890no
>>2065767how broke are you get bluemels they're like $40
>>206592726" made sense when rims could taco from big dropsNow big wagon wheel 29"ers are strong enough to not tacoEven women's bikes in size Small run 29"650B made sense to shuffle up the "All-Road" / Endurance / Bike Packing and early gravel bike daysNow they're all back to 700c700 x 28C700 x 50C29 x 2.4Those tires cover everything an adult bike should ever use, with absolutely zero performance disadvantage. From Tour de France, to causal rides around town, mild trails, to gnarly shreddy descents And a ~2.1-2.3" XC MTB does it all
>>2065933the singletrack that I can ride out of my back yard happens to be incredibly narrow, techy, rooty, with sketchy uphill switchbacks and I still prefer the nimbleness of 27.5 for this one exact trail. admittedly my 29er is pretty old now and geometry has gotten much better in the last five years
So I'm selling my bike saddle online and I want to add a note to the package. Im not the most poetic person so, suggestions for two or four more lines to add to this (should fit on a post-it note)? >This saddle’s seen a crack or two,>But now it’s starting fresh with you.
>>2065966quoth the gptpoet;A saddle, cracked and cursed,By rain and sweat quite reversed The seller swore, "it's fine! A relic, near divine!"The buyer quite soon rode a herse
>>2065968The saddle is not cracked though, it in prestine condition. Only seen a bit of my sweat..that's it.
>>2065969A saddle aged like fine wineA seller who can't even rhyme Got mogged by a frog and then drowned in a bogSoon after wasting everyone's time
>>2065970Tsk tsk. Very rude. This saddle's seen a crack or two.But now it's starting fresh with you.It’s hosted cheeks with gratitude,And taken pounding - call it rude.Scuffed from miles of ass-phalt sin -Straddle up and settle in.I'm also thinking: Saddle seeks ass-ociate.Mine was rejected.Yours could be elected.which one?
If bigger wheels are faster then why isn't every bike 60" or larger?
>>2065975because small wheels can be fun, depending on the intended purpose/terrain and are lighter.
>>2065975>monkey paw curls
>>2065977Who the fuck said that Cycling is about fun? Even if you're a utility cyclist, you would benefit from more power, higher speeds, and being able to actually ride on the road at a respectable speed.>and are lighter.Oh. Okay. Enjoy your 3" ((((E-))))scooter wheels faggot.
>>2065980If you're a utility cyclist, you would also benefit from quicker acceleration and a smaller turning radius while carrying more load. Youd have to stop at a red light ever 10 minutes and would not get to use the full potential of your 60'' plus wheels anyway.
>>2065982>Youd have to stop at a red light ever 10 minutes Literally just don't live in Niggertown, Canada.Works on my machine.
>>2065984>Works on my machine.He said as he topples off the cliff, his drag-heavy 70-inch wheels and cargo rack—50 inches above the ground—snagged by a sudden gust of wind.
>>2065991>cargo rackReal cyclists don't carry cargo.
>>2065992Not about utility bikes anymore? How do you compensate for those drag-heavy wheels and all that extra weight spinning with every pedal stroke on your sleek road bike?
>>2065994I use my legs, because I am an actual cyclist and not some e-scooter faggot.
>>2065995well then have fun breathing in car fumes on that motorway of yours
>>2065974I'd really avoid something like that
>>2065974You sure? I just want to thank the buyer since the listing was up for like half a year. How about this? Saddle seeks a thrust-mate, Mine, too skinny a gate. Yours might bear the perfect weight. Not sure, if "cheeck-mate" is better.
>>2066000Meant for>>2065999
>>2065995What is the brightest light I can reasonably mount to my bike? I tire of cracker olds, and niglet zoomers constantly driving with their highs on, or worse, simply not getting their ridiculous laser projection headlights never adjusted and even their daytime runnings being aimed directly into my eyes
>>2066000>note"now you and I are butthole cousins"
fucking threaded fork is a pain in the ass. Should I just say fuck this shit and get a 1" threadless fork? carbon even?
>>2066103what about it is bothering you?
>>2066105For me it's finding a used fork that is the right length and has enough thread to accommodate the stack heightLike if your frame is a weird size and didn't come with a fork
>>2066105what this anon said >>2066106I already have a fork but it was cut too short. I thought about buying a low stack headset but idk if it's gonna fix my problem.I'm just fed up with it getting loose and not being able to use 31.8 dropbar+stems.I tried an adapter and it was creaking loudly. Innicycle's conversion kit costs more than what I'm willing to pay for an unknown steel bike.
>>2066106the way you worded it implied the one you already had is the problem.iunno, if your local co-op or eBay doesn't have what you need, yeah, going carbon threadless might not be a bad idea.might want to check Soma, I believe they still make threaded forks.
>>2066108I have not checked in many years but the last time I did, uncut 1" threadless forks were already unobtainable. I've seen exactly two carbon forks of that sort in community marketplaces. I have one tucked away just in case I need to ransom a foreign potentate.
>>2066114Columbus minimal is still available
>>2066132That's a very attractive biek and also looks excruciating to ride, I salute those who suffer for fashion
>>2066139>excruciatingI agree if you're talking about the gearing.everything else looks a lot like my bike, and it's fun to ride
>>2066148The gearing, the crank length, the tires, and the seatpost. It's like seeing a cute girl (male) in please-fuck-me-daddy heels. I know what she likes, I like that she's not afraid to show it no matter how kinky it is.
>>2066151ah, yes the tires are too thin, I missed that. but I have that crank length (I'm tall, though) and an aluminum post. about the same saddle-to-bar drop, too.
>>2065618Never ever seen that. Ever. I know it's real, but I have never seen it. Not even in Wisconsin where there's sand salt and snow
>>2066132>stis and friction shifters
>>2066172just because they're downtube doesn't mean they aren't indexed. but yeah, those are brifter levers on the brakes. I mean, why not just hook them up?
>>2066172the newer shimano brakes pull more cable the brake only lever they sell doesnt
>>2066176I thought brake-only was only available left/FD?
>>2066172it's a parts bike ladsomeone slapped it together from the useless bits they had in the binthat's the flexor the joke, from a certain point of view
>>2066151You have good taste in women (male). She's beautiful
>>2066151based>>2066174because people who still use downtube shifters despite having money for high end stuff are ultra retrogrouches that believe it's somehow better than modern indexed shifting >>2066185>useless bits they had in the binif you have dura ace level parts and carbon rims you have the ability to hook up a shifter cable to a brifter>>2066161that usually happens when you actually use your bike daily instead of maybe once a week if it's sunny out
>>2066214>that usually happens when you actually use your bike daily instead of maybe once a week if it's sunny outi use my bike daily, bought it just before winter, and have been biking around 20k total per day 5 days a week and not experienced any wear on the rims themselves. i've gone through like four sets brake shoes in under 6 months but the rims still have fucking factory paint on them (i actually wish they didn't, my braking performance on the rim still using rim brakes is fucking horrendous whenever it is slightly wet out and i literally have to warm up my brakes going way slower than i have to on the first hill to get them to work properly)
>>20662147400 brifters are really ugly
How fucked am I?I'm restoring an old touring bike, and I just ordered a couple hundred bucks of new gears and such.Then I find a little tear, and some sanding later, quite a big tear, only on the inner side.You guys reckon this will stand up to some light use, around-town type stuff?The frame has some sentimental value, so I'd like to keep it.It's aluminium btw
>>2066253It's fucked
I took a spill on some ice. I thought I was fine, I even did a military fitness test thing after, but it was bad enough that I fell on my wrists/hands and belly and broke the mirror and light off my front fork. It was bad enough that my gloves were cut up from bracing my landing, which is to say it wasn't so bad I jammed my wrists or anything. The only pain at the time was in my knee.But today, my arm fucking aches a ton in a spot it usually doesn't. Is it normal for injuries to only start hurting a day or two later? Did I fuck up my arm mildly? Can I take this as an excuse to take a day off of work?
>>2066256>Is it normal for injuries to only start hurting a day or two later?yeah>Did I fuck up my arm mildly?this ain't webmd but danger signs would be like severe swelling and/or shooting pains. you'd know if they were shooting. >Can I take this as an excuse to take a day off of work?I've never needed an excuse>my gloves were cut up from bracing my landingdon't brace falls with your hands, your wrists will break and then you are really and truly fucked. if possible you want to try to brace with your forearm or upper arm and best of all is to let the bike soak the damage.
>>2066261>don't brace falls with your hands,I foolishly used my front rim brake to just try to just modulate speed (i got a disc in the rear) but there was ice I didn't notice; the front wheel slipped and kicked out so I basically did the world's slowest dive and landed mostly on my palms and then belly, but the bike itself hooked me so the knee that hit first felt bad for an hour or so. I couldn't have been doing more than 3kmh, I was crossing a road at walking speed, it wasn't a crash, just a slip.>this ain't webmd but danger signs would be like severe swelling and/or shooting pains. you'd know if they were shooting.I been drinking today and it feels better now that I'm fucking trashed but testing mobility, fine things with one arm feel bad on the other. it's not debilitating and the time off thing was mostly a joke, but I wonder if it was sleeping wrong or a problem I just somehow didn't notice
>>2066264
>>2066253>The frame has some sentimental value, so I'd like to keep it.then keep it as a wall-hanger and find another frame for those shiny new parts you got. you're not gonna find a welder who's skilled enough to fix that but also dumb enough to take on the liability for it.
>>2066255>>2066267Yeah, I'm probably canceling my parts-order tomorrow, and buying a whole new bike instead.I was trying to talk myself into it being fine, but it's not.Sucks for sentimental reasons, but it's also going to be a lot more expensive.Enjoy a macro shot of my pain
>>2066268If this was carbon that would be an easy repair
>>2066269How would that work? If the fibers are cracked like that, it's going to be weak there I'd imagine, even if you epoxy it close (or however that works).And that frame is over 30 years old, so I can't be too mad about it.
>didn't realize a the old frame was out of whack>dish the wheel to fit it>ride a while with everything centered>crash the frame>get a new frame>it seems properly centered now but I have to re-dish the wheel>make it egg shaped instead>loosen all spokes and start again>it fits but it's not centered>realize the dropouts were out of alignment and fix it>dish the wheel againI just want to ride my bike
>>2066253that's called a chainstay, btw, not a rear fork. the ones that go up to the seat tube are seatstays.it wouldn't hurt anything to show it to any local welders that do aluminum, or framebuilders if there are any. the worst that can happen is they'll say no.an anon has made a case against welding aluminum because at the factory they're heat treated after welding before paint, so allegedly any fixes aren't going to be strong.I'm not saying I believe it. personally, if I could get a bead welded over that crack, that would be good enough for me. but maybe I'm an idiot.
>>2066256>Is it normal for injuries to only start hurting a day or two later?it's fairly common
>>2066270they put a large area of epoxy centered over the crack, then lay fiber sheets over the epoxy and repeat with more sheets and build it up the same way it was made originally, more or less
>>2066271it beez like dat sometimes
>>2066274I don't know one way or another whether it's weldable.But frankly, if I'm at the point where I'm having to contact specialty aluminium welding shops, then this side project has become too big.I'll keep the frame and maybe try to get it welded when I have more time.>that's called a chainstay, btw, not a rear fork.Fair enough, I translated that directly from Dutch without considering terminology differences.I do feel like that piece of metal is more forky than chainy, but that's your business.
>>2066276not entirely correct >>2066270Go check out calfee Like repairing any epoxy-fiber composite material you cut away the damaged tubing, add some inner tubing for reinforcement if called for, then glass it back up, sand to flush, repaint. It's not even difficult, just messy and laborious. Things get more difficult if there's a BB or headtube involved but the same principles apply. all the "steel is real" memeing? total bullshit
>>2066265well that's right out, I went into work and did a fitness test like an hour later
>>2066253didn't even read the post but looked at the image. would not ride without at least some Bondo™ and hose clamps
>>2066279it's funny how out of touch steelisrealtards are about repairs, like someone is actually going to hammer their dented tin can back into shape but somehow carbon fiber is this unknown substance that aliens gave us that nobody knows how to work with
>>2066282rent free
>>2066282this fully thisery goon sire
>>2066264Im sorry, front rim rear disc? Do you have a picture?
>>2066325no but imagine a bike that has rim caliper brakes on the front wheel and a (mechanical(cable)) disc brake in the back.i chose this arrangement because my front fork is chinese nonsense that did not have a reasonable way to mount disc brake calipers but the back is old enough that it has the correct holesi actually really like it, the front brakes being a little weak lets me control my speed finely but then if i want to stop instantly i can do a little hand workout and completely lock the rear wheel if i want to. whereas even if i did have front discs, it would be harder to stop only a little bit and jamming on it would cause my suspension to collapse so hard it clips out of bounds whilst i do a front flip
hi, I've never used carbon paste before.is it supposed to be gritty? I guess that would grip it, but I bought cheap chink paste.
>>2066426I've only ever tried finish line brand and whatever came in the small ketchup tubes with my canyon but yeah it's like if you mixed vaseline with several different grades of sand
>>2066427ok, good. the tube is in moon runes but I went to the ali page and it says it's supposed to be that way.thanks, just checking
>>2066328why
>>2066081Outbound makes some good wide beam bright lights that would probably hit the mark, that's a 2200 lumen light. High mode on small battery lights usually means very short battery life though, a 2 cell lipo can easily put that out but you're probably looking at sub 40min run time. The Fenix BC30 would be another good option here since it has a wireless remote, you can run it on low/med with reasonable navigation lighting and then click the remote to get a 2200 lumen burst.>>2066256Yeah bruising and swelling (inflammation) happen after the fact. Deep bruises can also take awhile.RICE isn't actually the end all be all. Some amount of inflammation is actually good for your injury as your body is pumping more blood and thus everything it needs to rebuild soft tissue. In addition, some movement is good for a limb especially since again it helps get fluids moving, not just your blood but your lymphatic system as well. It will also help avoid scarring in the joint. Ice and NSAIDs should only be used if the swelling makes movement impossible or painful, ideally I would just stick to tylenol. Compression and elevation still fine.
Will a 2x road front derailleur (70s) work with 3x chainring (late 80s)? Friction shifting btw.
>>2066426yeah the grit helps with carbon paste, it adds friction so things don't slip when not torqued down as hard as alloy parts/frames can be.
>>2066523No the cages are different shapes
>>2066523well, throw it on there and find out. max out the limit screws and see if it'll cover the spread
>>2066500The thing with painkillers is a lot of people have this superstition that all pills are always bad, but if you have certain kinds of injuries, you'll instinctively avoid moving the joint and that will lead to irreversible problems down the line if it's not dealt with. That's why NSAIDs are, arguably, overused by athletes, because you're going to make a mistake either by overusing NSAIDs or giving yourself a permanent mobility issue by avoiding pain from flexing the joint or whatever.This is where an actual medical doctor, preferably a sports medicine specialist or orthopedist, so you can get xrays, MRIs if needed, and they can tell you if it's the kind of problem that needs to be moved, or left alone, or left alone for a while and then moved. If it's a significant fracture, you probably do legitimately want to not move it until it starts to callous, and then do light ROM movements during the last 3/4 of the healing cycle (which can be about 8-10 months). If it's something lighter, you can probably start the movement sooner.

in actually cycling (sorta, i have an ebike, im lazy) i have become a militant cyclist and got into the numtot bike youtubes and goddamn they have the most surface level bullshit takesare there any good radicalizing resources for cycling or urbanism that aren't just "lol dutch look so nice :)" because i wasted like 20 minutes of my life listening to that Not Just Bikes retard try to say that the reason finns bike in winter and canadians do not (this is false; canadians bike in winter too) is because muh urbanism and not because the places people successfully bike in winter are mostly flat but more importantly have stable but cold temperatures that result in a certain type of surface that is hard with some give (as opposed to fresh powder over ice that will laugh at both your studded tires and God, or wet snow which will just eat all the energy you put into it with the rear while laughing off all attempts to not slide side-to-side in the front)
>>2066551Probably because canada has fresh powder over ice that will laugh at both your studded tires and God, or wet snow which will just eat all the energy you put into it with the rear while laughing off all attempts to not slide side-to-side in the front
what kind of bike should i be looking for? i want something that can go off road (not mountain bike trails, more like 4wd tracks and fire trails/hiking tracks) and can hold some bags inside the frame. it needs to be able to hold a fair amount of weight, think a 100kg rider plus 20kg of cargo plus the weight of the bike. it also has to be basically fully serviceable in the bush somewhere. im looking for something i can go bikepacking with basically, but the ones i see online have a fairly low weight limit and im hoping i can get some advice here
>>2066567nta but that happened to me last year. usually my beater winteer bikes are alright in the snow with the tires deflated a bit and stubbies on. but this one snow fall, the snow packed up my brakes, stuck to my tires and wouldn't fall off. i made it 2 miles before saying this is fucked and had to walk my bike home anyways. i never saw snow that sticky before, it wasnt even deep
>>2066551>canadians bike in winter tooif you want to have good long chuckle fire up strava heatmaps and examine where canadians bike in winter
>>2066551>as opposed to fresh powder over ice that will laugh at both your studded tires and God, or wet snow which will just eat all the energy you put into it with the rear while laughing off all attempts to not slide side-to-side in the front)We have that in Finland too. In addition of few months of slush and icy slush.I think why people cycle is because of few factors:- our cities are really small compared to big cities in America or Europe, and like you said flat- pedestrian paths that get ploughed- it's common for kids to cycle to school- for students, or young adults in general car can be too much of an expense especially if you live in urban area so might be easier just to hop on a bike you've owned since you were like 15Funnily enough, not just bikes crowd tend to fawn over one city here that has lots of light traffic paths that get maintained a lot over winter.
>>2066580Its BC isnt
>>2066161It is what happens when you use very worn out brake pads. Bikes with rims like this came in occasionally at the community bike shop I used to volunteer at, brake pads were generally worn down to steel stubs of just the mounting screw. The ridged/groove wear pattern is caused by the steel plate in the pad, but it is thin and wears which causes the concavely curved/ridged wear until all that remains of the break pad is the mounting screw.
>>2066580>stravatechbro-adjacent freds are not true cyclists
How bad of an idea would be oiling my bike with rapeseed oil?
>>2066634It will work for your chain but not so good for bearings unless you are ok with cleaning and relubing constantly. Oil is not magic stuff and veggie oils work just fine, their main drawback is that they polymerize (dry) and once they do that, cleaning is more work but most of the common veggie oils take months to even start drying so as long as you keep riding, it wont be an issue.I used olive oil on my chain for a couple months years ago when I was broke, it attracted dirt more than I would have liked but was easier to clean than modern chain lubes and lasted longer, so, not so bad. Lard or tallow will probably work better and wont dry if you have that, also not great for bearings since it gets thin and will run without much heat but better than veggie oils. Wax is another option, great for the chain but useless for bearings, a bit of a pain to apply in its raw form and really needs some additives but raw beeswax has some of those additives already, still a pain to apply unless you add more. Veggie oils and animal fats were our primary lubricants for most everything up until fairly recently, most of human history and we mostly moved away from them because we found cheaper options.
>>2066634Forgot to say that the main thing is to make sure to keep it clean, rapeseed might attract filth and if you let that filth build up it will wear things out, so if you do it just keep an eye on things, if filth is building up, clean and reapply. Oils are easy to clean, rub in some fresh oil and then wash with soap, it will be clean. Oils generally do a better job of carrying filth out of the bearing surfaces than modern chain lubes like PTFE based lubes, not as fast but last longer and gets the filth out of where it does damage as long as you don't neglect it.
>>2066634oil will go rancid and stinky/sticky
>>2066636>>2066634I used a rapeseed based chain specific lubricant back in 2010-ishIt would splatter and leave marks even after wiping off excess after every ride, and would polymerize into a ceramic, dirt-caked coating that at one point I just accepted as "the new paintjob"I would stay away from anything vegetable based
>>2066655Probably something added to the rapeseed base. Rapeseed is a non-drying oil, it will eventually dry to the touch but takes decades to cure if it ever, a mild solvent will easily remove it. When I used olive oil as a chain lube some dried to a film on the chain stay, cleaned off with turpentine without much effort, a light scrubbing. Veggie oils are on the thin side and will spatter, but you probably have more than you need if it is spattering. But who knows what they added to that rapeseed base, it might have spattered no matter what you did.
>lol RAPE seed its RAPE seed not canola its RAPE my bike runs on RAPE man !!!!!!!!!!!
>>2066668it splatterino'd everywhere, no matter how little was applied, it was teh sux...Good corosion inhibitors tho
>>2066683Canola has less lineolic acidor something
Do these work and are they safe? The frame doesn't have those two boses on the seat stayI've got a spare 26" wheelset I can slap onto my friend's bike and he doesn't want to spend money to get the correct size wheels.

>>2066576any alloy bike with wide tires should be fine, fatassstated weight limits are always lower than the bike can handle in order to lessen the liability of the manufacturer.>basically fully serviceable in the bushhow many tools and parts are you willing to carry into the bush? just bring a chain breaker and quick link, tube and pump, and a multitool that works with all the bolts you have. that covers most roadside repairs.
>do all you guys live in a favela in brazil or something?
>>2066699The one for the front brake probably works fine but I would not trust it on full extension. The rear would make me nervous even with the rack bosses, without the rack bosses it will be destroyed in short order and possibly damage the bike and/or rider in the process.Just offer your 26" wheel up for trade for a comparable set of suitably sized wheels in the usual places. If you have a local bike collective/community bike shop you can probably walk in and just swap them for the right size.
>>2066721yeah thats the same as not nigger rigging you bike to take the wrong size wheels with chinkshit
Chinese items>Nanlio solid alu forksGreat value, looks slick, nice machining, will probably fit 99% of suspension to fixed fork swaps. Would buy again.>TNT wide flat alloy pedalsGot them in blood red, very nice machining, super solid, no wiggle after ~300km. Definitely comparable to something 3x the price in the west. Will be my go to pedal.>elitaone carbon seat postVery nice carbon work, super light, super clean, no surface finish but whatever. I have to say however the saddle holding mechanism is DIABOLICAL to get on and fixed right. Still, once it’s on it’s on and the quality is definitely as good as something 3-4x the price in the west. Would buy again if I got a new bike.>no brand coloured alloy bottle holderWould probably avoid any alloy bottle holder off Ali, they all look like the one I have got and the bottom bit is all loose and rattley. Should just be a single alu rod so I don’t see how it could be broken or defective. I might try some of the carbon bottle holder offerings.>Westbike biking computerNice cheap wireless unit for just speed and a few other things. Dirt cheap, decent enough quality for what it is.>Rockbros tail lightSweet little unit that hangs off the back of the saddle. Kino aesthetic. Good light, good battery life, USB-C charging. Has a very cool feature where it glows brighter as you brake like a car light. They also do this mini pair that connect together with the main one and plug in at your bar ends. They all flash in sync and stuff, might check them out. Also has police mode where they flash red and blue LOL. Have to see how long it lasts.>assorted coloured bolts (discs, headset, stem cap, general accessory bolts, valve caps)I ordered the most purchased ones and they were all of good quality and cheap.

There are different wheel widths to this shit?
>>2066791the widths of the front and rear hubs are different because the rear has an extra section to accommodate a gear, or multiple gears. so rear can differ from each other, too.the rim widths can also differ for different width tires, but doesn't sound like that was a problem.
>>2066791iirc there are two different types of 20" inch wheels 406 and 451
>>2066793>there are two different types of 20" inch wheels 406 and 451Which one is the thinner one / what do I need for a Tilt 500 folding bike from Decathalon? I just asked on the phone and I'll need to order one from elsewhere, though I can get a refund for the current one assuming it is wrong.

>>2066796why don't you find the part number stamped on the old one and buy that?
>>2066799Wouldn't even begin to know where to look for it exactly, and I'd probably have to start by scrubbing it clean to even find any markings and I'd prefer not to do that.
>>2066802so just measure your rim diameter in millimeters. rim sizing goes by the innermost surface that engages with the tire bead, so the outermost edge to edge distance is going to be a few mm larger, but it'll be close enough to figure out which wheel size you need
>>2066803>20 x 1.75 Alloy Rim 14G 36H V8.5>189mm Spoke>100mm OLN>19mm internal widthI'm unsure which measurement is supposed to be which, but I'll give my old wheel a measure and see what it is.

>>2066807I'm not seeing a battery or motor in his pic, and he only said "folding" in the post you replied to.it sounds like you're just trying to find shit to get mad about.that's not healthy.
>>2066803As near as I can work it out (with my tape measure only doing inches) it's 2cm wide, or a hair over 3/4ths of an inch.
My taint hurts like shit when I get on the peloton for ~30 mins. And also my dick shrivels up and feels really uncomfortable for like 10 minutes after I get off. How do I fix?
>>2066817there shouldn't be any pressure on your perineum whatsoever. you may need a different saddle and/or other adjustments. trainers just suck though, consider switching to rollers.
>>2066817bad saddle. i changed out my saddle to a thinner harder more "pro" type yesterday and today's commute alone caused me so much gooch pain i think it has given me actual tangible anal damage
>>2066817>How do I fix?You can ignore the problem until it stops hurting and your dick falls off, transitioning has never been easier!
>>2066816jfc do you even know what the word diameter means
>>2066817I kind of love when my dick falls asleep during the ride and then on dismount the blood resumes flowing. It is like getting an erection and having a mild orgasm at the same time which causes an erection and on rare occasions, a mild orgasm.
>>2066827>>2066817This is how you get ED.Get this shit sorted ASAP
>>206683445 and no ED, still enoy when my dick falls asleep and the blood surges on dismount, sort of like being 16 again.
>>2066824Why the fuck would I be measuring the wheel diameter? Unironically, that's like the only thing I do know already: 20 inch wheel. The problem here is that I need to know the width, the last wheel was too wide at the middle, but I've no fucking clue what statistic on that listing is the width of that part or where I should measure it from or anything.
does a dynamo hub that works both ways exist? like one that i can use to power a small battery on cloudy days but on sunny days can be spun up by a small solar panel?
>>2066841O.L.Dover locknut diameter
is it worth getting a road bike if you live in the country side with inconsistent roads or should I look for gravel bikes
>>2066842no but thanks because I'm going to steal your idea and make it happen. Right now though, no, best you have is ebike with ebike with solar panel, maybe even portable solar panel if you have enough time to charge
>>2066847if it truely doesnt exist and youll actually make it happen post about it here, ill buy one if you start shipping before the year ends
>>2066844Huh?Also I did measure the wheel without the tyre and it's 16 inches diameter.
>>2066834Fuggg :-DDDIt's not my peloton, just the one at my gym. What do? I have one of these at home, would that help?
I'm looking to replace every single spoke on my wheels to stainless. I'm running 12g black spokes right now that are rusting out and bubbling under the factory coat. I was recommended Sapim spokes but I have no clue of what to do for the nipples. The current nipples are 19 mm in length and 5.7mm in diameter. Nothing comes close to that size I can find. If I run 14mm do I have to change the spoke length since it's way shorter? Will the 1mm smaller diameter of the spoke nipple also cause problems?
Spec sheet says that Super Record 11 (2009) has a max cog of 29T. Can you realistically push it to 32T without having a derailleur extender/wolf tooth?Forums are mixed on it. Some say yes and some say stick to 29/30T.
>>2066866no

This tells you the width of the axle you use, this is basic bitch size that's everywhere.>19mm internal widthThat is the one that tells you the width of the rim interior (where you mount your tyre). It's real close to your 2 cm measurement, and generally is used to decide the tyre width. (See picture) Which part exactly is too big for your fork? Can you try to draw the situation on paint or something?
>>2066887>Can you try to draw the situation on paint or something?
>>2066897so, the current hub is too wide. the pertinent measurement is the O.L.D., the over locknut distance (which anon earlier called the over locknut diameter, not sure if he was trolling or just stupid)so, yeah, you should be able to measure it with a metric ruler through the spokes. the locknuts are the ones on either side of the hub, not the ones that hold the wheel on the fork at the extreme outside.
>>2066842Copenhagen wheel, is pretty much that but no solar, stores power from your pedaling.
I managed to break a spoke tonight. I don't even know how. I set off, heard a weird noise, looked down and oops spoke is just dangling free.It broke at the mushroom head part, not the threaded nipple. How could this have happened so I can avoid it when I lace up a new wheel?
I know this is badBut will it kill me?Also I got these bars off an abandoned bike…
>>2066913Depends, how much of the stem is buried?
>>2066913well I wouldn't sell you insurance but I also doubt you can mash out a hundred watts of ftp so you probably won't die, more's the pity
>>2064118I finally got it - thanks for all of your suggestions. Kool stop tire lever, hair dryer to heat the tire, and I pushed the tire up against a wall to free up a hand.Took a bunch of dawn dish soap to get the bead to seat right, but tire is on and should be good to go when it gets warm outside again.What a mess
>>2066916if it is any comfort I just spent several evenings on a tire swap and I have the right tools and plenty of experience. tire/rim interface is much tighter today than it was a few years ago, never mind the old stuff. park tool bead breaker is pretty good....
>>2066916I would simply buy a new tire. even if i werent a lazy fuck all the effort to try to get it on first might have damaged the bead or it might be simply out of spec anyway, leading to further damage down the line
>>2066914Slammed>>2066915Being 43 years old and still talking to people like this
>>2066905So just to be sure I understand, I should measure from the thing I've highlighted in red to the one on the other side and that's me O L D?What part of said nut should I measure from approximately, the outer edge of it, the inner edge, or the approximate middle?
>>2066906>Copenhagen wheelno its not the same im looking for something that works exactly as a dynamo hub does, sapping a constant 20w or so. the catch is that there is a switch on the handlebar that either turns it off or adds 20w of power. there is a small battery somewhere on the frame and a small (maybe 40w flexible) solar panel on the back over the panniers
>>2066933Outer edge, like in this picture. To get your frame's OLD you'd measure inside the fork dropouts respectivel, anon.
>>2066930bold of you to rate yourself as people
>>2066941I don't have a single ruler for some fucking reason, but as near as I can tell it's about 7cm or slightly below. Might have to check a second time, hard to do with the spokes in the way.

>>2066994wait until you learn about how Si Units are defined...
>>2066996everything is measured against a pile of water the same shape as a tungsten bar held in a secret vault in france
>>2066997I was talking more about how si units are literally defined by other si units, making the whole system recursive technically
>>2066996si units are all derived from physical observations and repeatable math. if the world lost every measurement device and every exactly measured thing only si units would be recoverable perfectly
>>2066999>if the world lost every measurement device and every exactly measured thing only si units would be recoverable perfectlytechnically so would American Customary Units since those are officially defined by their metric counterparts (which does technically make the US a Metric country on a legal level even though the only metric units in regular use by the average American are liters and grams)
>>2067000>defined by their metric counterpartskekso the only reason youd still have measurments is that youd be stealing the work that goes into si units and then reskinning them?
>>2067001Again, on a legal level, the US is actually a Metric countryhttps://en.wikipedia.org/wiki/Metric_Conversion_Acthttps://en.wikipedia.org/wiki/Metre_ConventionI guess at that point it would just make more sense to use Metric fulltime. Speaking as an American, I actually think we're closer to a mixed system, like the UK, but the UK is still more metric than the US is, because liters and grams are used somewhat regularly here, mostly in the context of food and medicine
Can you guys tell me what this is for? Apparently for a rear basket? It's an old Raleigh.
>>2067000>Gimme a liter of Cola.
>>2066998its not. distance was initially conceived as being some fraction of the earth's circumference but it was later discovered that the earth is not actually round (on top of that just being impractical to do in a lab) so then it became the "FUCK IT, IT's AGAINST THIS PARTICULAR OBJECT" standard for a while. then later it became the actual wavelength of some element decaying>>2067004yeah another tube goes on there and bolts on and it's the pannier rack>>2067002canada is a better example of a "mixed system". the uk is just "imperial, but we have to publish scientific papers sometimes". canada is "if it's human scale, imperial, if it's not then metric"
Has "Please re-read the SI-brochure" guy awakened from years of hibernation?
Is this primarily a road cycling board?I recently discovered I like mountain biking/exploring and don't know what to get. I bought an Ozark Trail Ridge last year and I've put ~1500 miles on it primarily in the trails. I'm tired of trying to find a used bike and now I'm wondering what used bike I should buy.
>>2066999If the world lost every measurement device, we would have little need to recover the old measurements for a very very long time and in the meantime we would probably develop something close to the Imperial/US Customary that is ultimately rooted in the human body and simple proportions. Recovering the SI units would also require enough to survive for us to sus it all out from, which is not a certainty in your hypothetical. Eventually we would probably develop something like it but it could be quite different. Hypotheticals are a terrible way to make a point.
>>2067046>ultimately rooted in the human body and simple proportionsbut these arent exact, youll never know *exactly* what an inch or a yard or a pound or whatever was after measurments cease. if you know how the si units were derived (you can look these up online, there are too many to list) you can derive them again and they will be *exactly* the same as they are noware you trying to argue against this?
>>2067037>primarily a road cycling board?no>I'm tired of trying to find a used bike and now I'm wondering what used bike I should buyplease rewrite the question and ask again
>>2065530What's the best way to store a bicycle when it's not in use?
>>2067037/xs/ has a mtb general but it is not active right now because most of north america is in the off-season
>>2067052ideally you keep a vast mcduckish vault full of bicycles that you can swan-dive into from a height of no less than ten meters
>>2067052Would.
>>2067047So society is going to lose all of its rulers and non-metric clocks but retain the ability to measure the distance light travels in a vacuum in 1/299.whateverth of a second? Even going back to the old inaccurate meter defined by pendulum length would take years if not decades to sort out in the scenario you describe and no one would be particularly concerned about doing it because society has collapsed, shit has hit fan and it is every man for himself, eat or be eaten. Majority of measurement does not require much accuracy, carpenters the world over independently figured out that a good compromise for chair height for most people is the length from elbow to finger tip of an average person. Most every culture that derived a complex system of measurement ended devloping a system remarkably like everyone else when you get down to it and society was built on these inaccurate systems over thousands of years.The history of measurement and the development of the metric system is fascinating stuff and very important to who we are, seems a shame to assign it all to the dustbin of history. I for am glad there are holdouts and think we should have more than one system the world over and we do, common to see things expressed in football fields or car lengths; the daredevil on his motor cycle puts three city busses between his ramps because it makes that distance easily understood, not because he needs something to jump over, Guinness will put the distance down in SI but they will also say three city buses.
>>2067060you forgot to make an argument btw >inb4 no argument again not surprised
>>2067060>So society is going to lose all of its rulers and non-metric clocks but retain the ability to measure the distance light travels in a vacuum in 1/299.whateverth of a second?well when metric was introduced, it was measured in fractions of the globe's circumference, which "should" be trivial to calculate given astronomy (which was also well understood at the time) and that measurement only fell apart because it turned out the earth isn't quite round, it's a little wider at the equator AKSHUALLY
>>2067065And? Did you stop reading there? Anon said we just needed the definition and I even included the simplest historical method to derive it. Astronomical method takes considerably longer and more means of measurement than a pendulum, needs the sextant on top of having the clock and accurate star charts from a pole, the equator and where you are deriving the meter and accurately finding both the pole and equator require another measurement device, the compass. Both require averaging a great number of measurements for any accuracy, pendulum can be repeated more quickly which is why it became the standard until methods not affected by gravity on earth not being constant even if it requires figuring out the gram. This is all considerably more complex than reading a wikipedia entry. In the situation were we lose all forms of measurement we are no more likely to have accurate star charts than we are to have the ability to measure the speed of light, figuring out 1/1,000,000 of the distance between equator and pole would take considerably more time than using a pendulum.
>>2067076again what are you arguing? if humanity can derive si units once dont you think its possible that we can do it again? and i never said anything about apocalypse or whatever your burger fried brain is considering, it was a simple hypothetical posed to an anon telling everyone to wait until they learn how si units are defined. the fact is that they are defined infinitely better than any other unit system know to anyone
If I'm unsure on a frame size when buying online should I drop down a size or will this cause issues?
>>2067083It depends on your proportions and the bike. It will be lower and the seat won't go as high but that might not matter. there's benefits to it being smaller
>>2067085I think I'll just pull the trigger before I spend another night pouring over geometry diagrams sweating over mm changes.
>>2067083It mostly comes down to preference unless you are competitive and need that perfect fit for max power. Some find a slightly larger frame more comfortable and some find a slightly smaller frame more comfortable. The actual geometry also plays a role, different frames in the same size can feel very different, if one has no bb drop it will be bigger than one with lots even though they are the same size.Sizing down is the safer bet but let standover height decide, you want it at least an inch below your crotch when standing flat footed in the thinnest soled shoes you will bike in.
>>2067087>standover heightThats about the only thing not listed. They recommend a size M / 50 for my height, 175cm so I'm just gonna trust in that. Compared to my current bike which is on the larger side the stack is 20mm shorter which hopefully makes it line up. Would be nice to sit on it before I order but I guess this is part of the fun of building your own.
>>2067089You can calculate stand over height, easiest is just to draw the frame in any cad program or on paper with a protractor but all it takes is a little high school geometry to do the math. Just need to remember to add in some for tires. But the vast majority of people would rather have a frame that is on the small side than on the large size.Listing stand over is tricky especially in these days of disc breaks where frames can take different wheel sizes and tire thickness, probably resulted in lots of complaints from morons so they just started skipping it, anyone who really needs it can just calculate it and they will know how to adjust it for their wheels and tires. Lots forget the tires, I did on the first frame I ordered and now I prefer a frame on the small side.
>>2067083Do you have a current bike you can compare the geometry to? Buying the right size online is actually quite difficult mostly because it requires an understanding of frame geometry and how your own body feels while riding. Generally, dropping down is safer than sizing up, that answer depends however, human arm to leg to torso ratios vary greatly, almost uniquely to each human. The good news is as long as you're close to the standover height to your inseam, the bike can be fitted through different handlebars and stem lengths as well as saddle setback and crank length. Bikes are very adaptable, some more so than others, like sloping top tubes and short/long stays. Anyways, a "proper" bike takes time to fit
>>2067090>>2067091Cheers, a bit of maths and comparing it to my old bike looks like it should be around the inch of clearance. I also found something local in stock that has relatively similar geo and is also running 700x28 tyres so should be the same to sit on.
Whats the story with the groupsets on aliexpress? I've bought a couple over the years and outside of the lack of packaging they appear and work as well as the legit product just for half the price. Are they just selling them without the markup or where are these coming from?
>>2067098I would assume they either factory seconds or OEM like those tray CPUs you can buy

Is there any functional difference between r2000, r3000, and the 4700 brake levers?
I bought a brake disc and pads I realized afterwards I don't need, since the issue was between ground and screwdriver. Should I keep them as backup just in case, or should I return them ?
>>2067098not sure but another data point: I bought Microshift 2x7 brifters off ali for my old roadie that had downtube shifters and it's been nice.not sure if they're "real" Microshift or not, but if I were bootleging would it even be worth it to bother with 2x7 these days?
>>2067103no
>>2067103cable brake levers are basically all the same and there is only any reason to pay more than 20$ for a set if it has an integrated indexed shifter>>2067104yeah keep em, those are wear parts and you will want them someday. its not like they go bad. even rubber brakes could dry out but a metal disc and what is basically a block of sand and epoxy? throw it in the closet and forget about it and kick yourself when you do need them but forget you own them and order a set off of amazon
>>2067098yeah a lot of them are just the original factory selling stuff directly without the branding

How to find a bike seat that doesn't destroy my gooch?
saddle*
>>2067152trial and error. go to ebay. buy a few very different saddles which look notably flat made recently by brands like fizik, giant, wtb. do not pay more than $50. do not buy anything made by a traditional saddle brand like selle anything or brooks.
how do semi-slick tires like schwalbe g-one rs work outside asphalt?
>>2067168Pretty much like slicks but better on cornering and ruts. They will still try and follow any deep rut but don't mind shallow ones and you can ease yourself out of deep ones with a little finesse without the over steering and the subsequent correction of slicks. They are faster on well packed trails/roads than more suitable tires but you can't rely on the tire to bite in enough on a fast corner so have to be more careful. For casual riding/commuting they can be just fine and a good choice for those who do the bulk of their riding on pavement and just want a little more stability for that trail or dirt road that is part of their daily commute. Not a good choice if you want to occasionally spend a day riding trails or the like. There at least used to be some semi-slicks that were knobby on the outside, they are pretty good in all but loose gravel, but not so good on asphalt, pretty much the opposite extreme of your pircrel, you sacrifice cornering on the asphalt instead of on the trail. The middle ground between them tends to be be something like a good general purpose touring tire which handle most everything but mud well enough, jack of all trades tires, they are masters of nothing but get through most stuff without completely sacrificing performance on pavement.
>>2067152it is trial and error, but a couple things:super padded saddles make you sink down and more of your ass is now rubbing. a saddle is more like a perch for the 2 ass bones that support you. those 2 spots on the bulbous parts can use some padding, but the rest you want sleek so it doesn't rub and you can use the nose for leaning against when steering.your sit bone distance affects how wide will be comfortable. they have a diagonal shape the further up the hip bone you go, which means how far leaned over you ride affects the proper saddle width. pic is for BG™ saddles but shows how it works.the more upright you sit, the less engaged you are with the saddle. wide is better and more padding is not really a factor. full triathlon aero tuck means you're fully engaged, your proper saddle is just about the same width as your sit bones, and (apparently) a flatter profile is more preferable.but everyone's different so you can't just do the calculations and arrive at your exact saddle. gotta try stuff.
>>2067152do you use the correct saddle height?
>>2067171i see, thanks.i'm looking for something different than my current wtb resolutes that came stock with my gravel. my rides are mostly asphalt and gravel-likes but i also don't mind going thru a forest road that's a bit sandy (mostly pine forests in my area) sometimes. i was thinking of something that's better on asphalt and hard surfaces but also won't kill me off-road.
>>2067179Most any tire with a less aggressive tread than your Resolutes will perform better on asphalt and many of those will perform better off-road than semi-slicks. But we are not talking about the difference between your Resolutes and slicks here, Both the less aggressive tread and the semi-slick is less than optimal, need to find which compromises suite you and your ridding best.If you have much experience on proper slicks, semi-slicks can be kind of horrifying. When you lean into a corner on asphalt and the tire transitions to bearing on the outer tread, if feels a lot like a slick that is about to lose its grip and put you into the pavement even though it probably wont and is just the transition to the lower grip side tread. Some people don't mind this and most probably don't even notice it, but some really dislike it.
>>2067179I have ss gravel kings and ridden them on ice and mud no problems even on single track they were controllable I really don't understand how they generate so much grip
If I'm lazy and gay should I throw away my crappy tire "hybrid" with a motor on it and just get a 1l+ cruiser
My drive wheel is missing a spoke due to winter weather temperature-related stresses and also that wheel being actually bent. How long can I ride on it until I die, and will my death be the result of poor maintenance or just general lifestyle?
Guys my wheel broke bcuz of temperature
im radicalizing
>>2067211>BAWWWWWWWWWW IM TO RETARDED TO BUILD A WHEEL BAWWWWWWWWWWWWWWWWWKill yourself.
>>2067195Most surfaces don't require much grip, but you are not going to aggressively take a corner when riding on ice unless you have studded tires or stupid. We adapt to the situation and we would not be able to ride a bike if we didn't. Finding the right tires for our needs makes riding more enjoyable. >>2067211The weather had nothing to do with it. I rode a wheel missing 5 spokes for years. Missing a spoke in your standard wheel is not a big deal, especially the drive wheel, avoid potholes and like and you can ride forever on it. A new spoke and a spoke wrench will cost you $5 and you can fix your wheel. The wheel was not actually missing 5 spokes, 3 were still there, just bent around other spokes so they would not cause problems.
>>2067219>to retarded
>>2067159I may try this after some adjustments.>>2067172This was informative and I never considered all that.>>2067174I actually think my handlebars are too low looking at that.
>>2067235>my handlebars are too lowthe handlebars are shown in a general position, but the saddle height is only correct as shown. you can raise and lower the bar for preference and casual vs aggressive riding, but the saddle height is only correct at legs extended without locking the knees
>>2067211if the wheel is bent your already deadif you mean just out of true depends on how out of true but if its just a slight wobble you should be okay.
>>2066634just get gear oil it cleans the parts too

do you have to change the cassette and chainrings when a chain wears out or is it only the other way around
>>2067309chains wear much faster. you usually go through around 3 chains before the gear teeth start to go.
>>2067309>>2067312some people will argue a slightly worn sprocket will inadvertently cause chains to wear faster
>>2067313the solution is to replace all chainrings, cassettes, and chains every 100 km
>>2067313what about a slightly worn chain
>>2067313chains are cheaper and wear faster.so by your own logic you just replace chains even more often
>>2066999>this retarded, arbitrary non base10 system is so good, it might work if every ruler on earth suddenly disappeared
>>2067052chained outside on the street
>>2067219replacing a single spoke is not building a wheel
700c 28mm wide tire doesn't really have a clearance on steel fork at the top, and rubs there in one place. Should I just give up and get 25mm tire, or could I in theory file a 5 - 7mm concave relief in the protruding top tube?
