tpu or tubeless?
>>
I have a 26 inch fat bike that I want to swap the wheels for 27.5" skinny tires
The only problem is that it's an older rim brake frame
I already know the wheel+tire will fit in the frame but what I'm not sure about is whether or not the rim is going to line up with the brake pads, is there any way I can be sure before wasting my money?
>>
>>2069106
Unless I'm missing something the wheel is going to grow by .75 of a inch so measure if the pads can move up in their adjustment by that much?
>>
>>2069106
there should be plenty of play on the calipers and even if not you can literally just get new calipers that are longer.

what ?

are those amazon gas engine kits worth it?

You didn't choose to stop the ride, your flat TPU tube did.

spare tpu tube is less hassle to install than fucking around with a tubeless puncture

It's not an alloy frameset it's a complete bike but you'll probably want to upgrade to something faster and more fun like a grizl once you've gotten in shape:

https://konaworld.com/products/unit-36tk

It's designed to carry a bento box for the mid ride refuel. If you're looking for a good non-pinku bento box to go with it, ask /ck/. Make sure it's chibi (small sized) that will help you with the 256 lbs.

Tubeless. The first few times dealing with mounting and sealant will be a PITA but you'll get better at it just like you did with tubes. The thing is, it takes a LOOOOOONG time to get practice (like several years) because you will basically never have to do it. And a lot of the assumptions you make with tubes can no longer be used, like the idea that any tire can go on any rim. A lot of people get filtered by this and go back to legacy tech that sucks more because they feel that getting frequent practice dealing with problems is better than just not dealing with problems.

Why is it so hard to find 20 dollar chainrings
Why is there so much crap like speeds etc to match what a gross convoluted mess
>>
can you use motorcycle chain tool for bicycle and vice versa
>>
>>2069181
I think you could use a motorcycle one if the pin pusher is the right size but it will be suboptimal. Just buy one on amazon for 12 bucks. It has the tool that holds the chain together when you split it

I thought the same. I then gave TPU a shot anyways mostly because I hate tubeless so much. I have now nearly worn out my rear PZero and never had a flat with that setup. I've also done loads of gravel riding and bikepacking in the woods (my friends always include these sections but I only have this bike). It also holds the pressure better than I thought (went for a week long tour without a pump). Ride feel is great. Positively suprised.

>>2069161
Tubeless is heavier than a TPU setup + a million additional downsides on top. It serves no purpose and is dead.
Ever fucking rim is now "tubeless-ready" which makes tire mounting a massive pain in the ass for everyone.
>>
>>2069285
This board seethes at the mere idea that a bike part purchased for any reason whatsoever might also happen to be lighter than any other bike, yet 5g of extra liquid inside the tire is the straw that broke the Pogacar's back

"I have gone through my first tire without a flat" is pretty impressive though. I think it's been six or seven rounds of new tires since I got a flat but I've stopped keeping track, so get back to me in a couple more years I guess.
>>
>>2069290
Bro wtf is that first paragraph? It reads like you're going to make a contrasting statement but you never actually deliver one.
>>
>>2069297
The board doesn't like weight weenieism. So it's weird weeing someone get worked up over 5g of sealant here, of all places. Not sure why it's so hard to understand this.
>>
>>2069298
It wouldn't be hard to understand if you knew how to formulate a fucking sentence.
>>
>>2069102
depends on how wide you want to go and which tyre and wheel you want to ride in general. There is only like three fast tube type tires left on the market and putting a tpu into a TLR tire is kinda ret

Closest I have to strange is this Bianchi style of frames that not many know of in my experience. I really want one of these. Apart from that I'm building a rat bike this weekend. Rusted 700c hybrid frame that I'm building up as a deore 2x10 drop bar with stem mounted and suicide shifters. Again not really strange though but slightly unusual.

How many of you patch up tubes rather than just buying new ones? For many years I would just collect old tubes in a garage but not patch them because I felt that I would suck at it. Then last year I purchased all the stuff you need... I got sandpaper, I got the big jar of slime rubber cement, I got the Rema top of the line patches. Some of these patch jobs I complete successfully, but it seems like more often than not my first attempt fails. I feel like I do what I'm supposed to sanding the large area, cementing a large area around the hole and letting it dry, applying the patch and putting weight on top of it to press it down, but it seems to fuck up so much, especially around the orange edge of the patch.

Don't get me wrong, I have been able to save 12-15 tubes, but seeing so many of them keep failing, It's so frustrating.
>>
>>2069348
if the tube is old it's just generally permeable and hella over

if it's a rim side puncture it's over

if it's non-round hole (like a cut) it's over

also
>sanding
not usually necessary, just clean it with some isopropyl alcohol or something
>top of the line patches
you got pwned by advertising, just use a section of an old tube of similar diameter
>letting it dry
it shouldnt be dry, just tacky, only takes like 30 seconds indoors or on a warm and dry day
>weight
useful but not necessary. pro tip get a bag of those spring clamp things, they gud
>around edge fails
put more cement so it covers more than the patch, and put some on the patch too
>>
>>2069370
>>2069348
Why are you so poor? Just get new tubeless tires.
>>
tubeless is the one time the cycling world was sane enough to take cues from automotive but too stupid to figure out why a thing is indeed a thing and not take the one dumbest thing they could

it works on cars because cars have fucking wide tires would make a car "tube" prohibitively expensive to make properly since it wouldn't be round, and cars sit on flat tires which are further not amenable to inflated tubes. so instead you just have a stiffer tire that seats to the rim. motorbikes still use tubes on dirt bikes and scooters and even some sport bikes and you only see car-styled tubeless tires on sport motorcycles that are weight weening or have tire profiles that aren't very round, or similarly on dirt bikes with flatter tires or thinner wheels where again a tube won't be round and won't work great unless your tire has enough stiffening that you may as well just seal and inflate the tire.
>>
>>2069158
any random stolen ebike off of fb marketplace but then just take the electric parts off.
>>
could you do tubeless without sealant or will it leak air or something?
>>
>>2069382
it's very likely to leak because bike wheels have spokes that stick into the rim creating a bunch of tiny airgaps for air to escape from. It's the same reason a lot of antique cars that have spoked wheels (such as the Ford Model A for example) tended to use inner-tubes as well.

I have a Lemond Zurich 2002 frame. It is in decent shape with paint chips and rust on the cable stops.
Should I get it restored or just leave it be? Getting the paint restored would mean 4 months wait time but it would be getting a modern paintjob and all that comes with that. But I really want to ride it ASAP.
>>
>>2069385
You could probably get a second frame for the price of a decent paint job

Yes it is just fine to. Sealant is just cope for retarded ebikers who dont know how to true a wheel.

>>
>>2069382
depending on the tire it's possible but it's not ideal. the sealant welds itself to the tire bead and that's a significant source of slow air loss

Theres a difference between 11-spd Road Shimano freewheel bodies and 11-spd MTB Shimano freewheel bodies.
Now my new 11-spd (apparently road) cassette doesn't fit on the used wheelset for gravel use I bought although the seller said it fits 11-spd. rrrreeeeeeeeee

I was going to with garbon riros for my shartmart shitbike thing but the power of the aliexpress machined aero chain ring was too great.

When I go on a longer ride and get off the bike it feels like my body cavity is trying to suck my penis into it from behind. Is this normal or is my saddle the issue?
>>
>>2069414
Usually people blame the saddle itself when the saddle position is the real problem. Try moving it forward a bit before you fall down the rabbit hole
>>
is it true that britbongs have front and rear brake levers the opposite side to normal people?
>>
>>2069416
Australia and new zealand too

>>2069348
I patch everything until there's a leak close enough to the valve that I can't patch it, or maybe like a long tear or something.
it sounds like you're doing it right. it is tricky to pull off the backing near the edge. if your backing is thin plastic instead of foil, you can just leave it on.
also, you're allowed to pull off the failed patch and reglue the tube and put a new patch on.
blow on the glue and make sure it's dry? it will look cloudy. you probably are but anyway
>>
>>2069385
ride it
>>
>>2069416
Front brake and rd on the right fd and rear brake on the left because those are less critical
>>
Can you make a chain whip tool with old chain
>>
>>2069416
Actually it's right motorcycles use that layout
Also you're right handed which you should be you're dominant hand will be on the dominant brake
The opposite is actually gay french shit that you shouldn't brag about unless you also like cocks going in your bum
>>
>>2069441
>>2069416
afaik the Motorcycle Thing is right hand is one set of brakes (usually front) and left hand is clutch, and your "panic" brake (usually rear) is on a foot pedal/striker. or maybne the same thing but left-right mixed up

actually, i have a shitty e-bike im ordering an even shittier 2-stroke engine for; what is the "correct" arrangement of controls to emulate a motorcycle in case i ever actually get a license instead of oper8ing illegally? fortnine keeps telling me to buy a REAL bike but not how to construct one
>>
>>2069441
it just makes the cabling logically consistent during the original downtube shift days when you couldn't just move the shifter and bend the housing over to the other side of the handlebars.
so: front shift and front brake left, rear shift and rear brake right .
>>
>>2069437
sure
>>
>>2069455
either way you were using either a plastic tube to semi-artifically increase bend radius, or were a psycho with frame levers. the difference in travel is minimal swapping from left to right.
>>
I've got a 3x7 gear system, and while riding on the first and third front gears runs smoothly, the second gear doesn't seem to catch properly at all and the chain jumps around. I've tried adjusting the cable tension, cleaning the chain, and replacing the front derailleur (which I needed to do anyways, regardless) and nothing seems to work.

The only other answers I can think of are replacing the actual gear shifters, or packing the rear hub full of grease. I thought I did so when I last took the hub apart to clean and regrease, but maybe I sucked at it and didn't know.
>>
>>2069437
People do it with old pieces of wood. I did it with an old handlebar. Will post pic when I get home
>>
>>2069461
How is packing the rear hub full of grease going to fix your front shifting? If your 2nd front gear is working like shit consider your chainring could be worn down. Im only guessing that's the problem because you write like shit.
