There really isn't too much stuff to learn. It's just that everyone here Tries to spare you the learning curve. You're free to just go out with whatever you have and learn by yourself like everybody, having a flat and buying a spare tube at the first shop, getting your bike stolen etc etc.
hope I dont get it stolen, can't really afford it
guess I'll just ride rentals if that happens

>they also ride like shit and are probably the most expensive tires you can buy
This makes me know you've never cycled that much with them.

I've had quite a lot and they make pretty damn good tires at decent prices. I don't know how if you're based in the US, but in Europe, these are not that pricey.
marathons 100% do ride like shit if you're tlakin gabout that then you're cope but they obviously also make nice tires
Best place for tire deals here in the US are used, ebay, or whatever webstore ships here. CRC used to be good before they stopped shipping here and died.
Generally I find kenda's to be cheap(and decent) while conti's, schwalbe's, and maxxis are overpriced(imo).
Vittorias seem to go on sale, and some bontrager and specialized tires are actually good.

WTB used to be my favorite brand but they killed most of their 26 stuff, which I liked....

I think it's a bot
I hear ya but I still don’t know if a stadium is quite worth the public investment. Again, it would be worth it if they stuck some apartments in it like The Battery in Atlanta.
>The stadium tax was voted down in a county referendum
Good. If the team is making enough money that turning the stadium area itself into a mixed-use development is a desirable option, they should be able to do it without city gibs. I'm personally tired of cities bending over backwards giving sportsball teams and corporations handouts for building stadiums and data centers.

>I’d get behind it if it was like that Atlanta stadium that also had apartments and shops mixed in.
The Atlanta one was not a success. The Battery isn't walkable or bikeable from any of the nearby neighborhoods, and it isn't connected to transit, so the end result is that it's still more parking garage than anything else. All the residents need cars to go anywhere, all the visitors for games need to park, and now since there is 0 transit connection to the heavy rail game nights utterly fuck traffic on the top end of 285. Outside of game nights and occasional conventions across 285 at the Cobb Galleria the place is a ghost town because there is 0 reason to go there.

The Battery is fine. It’s not super walkable because of the location, not because of the building concept.
Take a Batery concept and put it right in the middle of downtown KC and it would obviously be walkable. You just sound like you’re strawgrasping.

what's the advantage over nice dual-pivots?
They're retarded light and retarded expensive. The silver pair I have are from aliexpress. They were 140 for the pair but I guess they wen't up. Let's see if I'm still alive in 6 months.
so, lightweight but not particularly better braking performance?
count me out .
A common (validated) worry with truly lightweight brakes is actually that some braking performance has been sacrificed on the most retarded altar of marginal gains. You want nice stiff brake arms that can transfer leverage.
UK AliExpress has something similar for £38 that I will not buy because of >>1997472 being valid

dual pivot is a broad description, there are still a lot of possible design variations and braking surfaces make still more difference but the best mechanical rim brakes I've ever had were FSA K-Force dual pivots with blue swiss stop pads and DT Swiss ceramic coated rims
almost the same modulation and peak power as hydraulic

You have either not read or understood my post. Youre quoting 'braking power' which is limited by the construction of the braking mechanism alone. As such it is not the determining factor for braking performance. It is TRACTION retard. Which is linearly dependent on MASS. While kinetic energy is lineraly dependent on mass and the SQUARE of velocity. D'uh.
Example for retards who cant into abstraction:
A 40 ton semi will come to a complete stop in 40 m from 80 km/h. This is at least comparable if not on par with many passenger cars. Both are entirely capable of locking up wheels at this speed. Thus traction is the limiting factor.
Now if we, like you seem to presume, imagined braking distance to be lineraly dependent on mass, we would expect the 40 ton lorry to need 800 m to come to a stop compared to the 2 ton passenger car stopping in 40 m.
On a sidenote: Assuming equal reaction time the distance covered before the brakes are applied does increase linearly with velocity.
Your example concerns the ridiculous premise of 'what if a tram and a passenger vehicle were equipped with the same braking mechanism'.
Anyways neither belng on streets. One is just a bit better than the other.
>Your example concerns the ridiculous premise of 'what if a tram and a passenger vehicle were equipped with the same braking mechanism'.
The tram is going to have more powerful brakes than a vehicle, but not on the scale of thirty times that amount. Basically, the sheer mass of the streetcar (78,000 pounds as per the official website, or 35380.205 kg), blows anything by a personal vehicle out of the water.
You just presented two calculations that both imply you believe both vehicles to have equally strong brakes. You also insinuated that braking force would be somehow determinant of the stopping or braking distance. And now you're trying to missrepresent what I have claimed and I am pretty sure it's not accidential.
I have no expertise in tram or train engineering and don't wish to have any points of contact with such objects. Yet I am pretty sure that their design is sensible. And a sensibly designed vehicle will have brakes that, at expected speeds of opreration, have the potency to lock up the associated wheels. This then makes whatever traction there is the limiting factor and there will be ample reserves in terms of mechanical brake performance for every situation.
IF we then assume one of the streecars that employ what looks to be pneumatic tires then it would follow that compared to a passenger car that was equally sensibly designed it would solely be velocity that determines braking distance. A point that too was originally contested >>1997451 in a manner that made an attempt to insult a third anon and aparently the goalpost is sick of it by now.
Steel wheels on rails: I dont know, I imagine less friction but don't know and I won't look it up because of someone like (you). Ask the train autists if you really want to understand physics, which you ironically suggest others don't.
On a sidenote all of this is completely besides the point the urbanists are trying to make. If everyone parricipated in their idea of motorized and thus no less degenerate form of transportation streets would be alot less busy in terms of traffic volume and thus safer.
Also: Lower speeds still decrease the distance covered during reaction time. At higher speeds a braking mechanism might become entirely useless in cases where a vehicle is about to collide with a pedestrian.
It's just sad to me at this point. I fled Texas for Madrid, and I don't know what there is to say. It's just a night and day difference in living. I think I'm pretty fair too, I can acknowledge the cons. Trains can frequently take longer than driving, and sometimes they're totally packed. I groan when I see a packed train pulling up to the platform, it's going to be uncomfortable. But it's a different kind of discomfort, I read a lot on the train now. When I would drive before, I would hit an unexpected pocket of traffic and what I'd worry about is my wasted time, because I'm stuck in my car paying attention to the road. Even in a packed train, I just read, and the train still arrives in the same amount of time. My time never feels wasted, I always feel like the train is time for me to gain something through reading. This lack of fear for my time has just caused my daily anxiety to plummet.

I also understand this requires dependable transit, which Madrid has almost always delivered. Some cities don't deliver that. But if I'm given the choice between the two, a car or dependable transit, it's just not a contest. It's also incredibly cheap. Cars seem transparently for specific use cases now, like living in rural areas, or for the disabled, or for people who frequently need to haul lots of big objects for work. Just living as an average person in an urban area should not need a car, that is a totally dysfunctional kind of city. I thank God I was able to leave, Spain feels like civilization. I love the Texas countryside, but the cities feel like some kind of political abortion now. Like the cities were made to benefit car dealership dynasties, the banks supplying credit for these depreciating assets, and to avoid confronting political tensions around new development by just constantly sprawling out and away.

the same people who resent stuff like paul will love to tell you all about their exotic 90s bike (so cheap!) which would have been outrageously expensive when IT was purchased new.

I say god bless anyone who buys the fancy new shit which actually has a long lifecycle because on the used market it becomes reasonable to buy and everyone benefits.
I smoked a pack or two a day for about 10 years while I cycled. Then I quit smoking. It's been like 3 or 4 years since I got into a smoke habbit. My cruising speed on the road bike is now 22 mph. Successfully kicking the smoke habbit is the best thing in my life.
yeah smoking less weed makes me so much faster on the bike
Yeah, I smoked for 20 years. It was time. I used a vape pen then stopped using that, too. Made it very simple.

I wouldn't know, I've never quit smoking reefer
not quit just stopped smoking by myself

>I want to buy a new bike. What should I watch out for?
Don't buy Wal-Mart garbage.
Don't buy department store garbage.
Beware of amazon and alibaba garbage.

>Should I buy from Bikes Direct?
If you are clueless enough that you need to ask, no. If you have no mechanical ability, no. If the alternative is walmart, maybe. Ask first.

>I want to buy a used bike. What should I watch out for and where should I buy?

Craigslist is good for old bikes. Pinkbike.com/buysell is good for used modern mid- to high- end mountain bikes.

So a shop near me has a good deal on a nice (prestige name, high modulus carbon) gravel bike with the groupset swapped out for something less glamorous but still totally fine (I'd rather have a nice frame and good enough groupset than a shit frame and top end groupset, and I can't afford a top frame and a top groupset).

I'm not desperate for a third bike but I do intend to get one at some point, and I want something that's ROUGHLY in the same ballpark as my main bike (a road bike), so this could actually fit into my long term plans pretty well.

But here's the thing. I took it for a ride and while it felt really stable, it also felt a little unresponsive because of the ginormous knobby tires and cheaper wheels compared to my road bike, and flared meme bars. So it was hard to make an apples to apples comparison.

The geometry is in most ways extremely similar to my road bike. the main difference is chainstay is 15mm longer, everything else is within 2-3mm or less than 1 degree. Slightly longer headtube, slightly more stack. Oh and obviously quite a bit more tire clearance, though I don't really care about that (if anything it's less than ideal, I don't like big ass clumsy tires)

What I'm wondering is, aren't gravel bikes supposed to be all about low speed agility? On the one hand balance was piss easy at low speed, but the handlebars were really slow to turn and it felt like tight corners were something of a challenge. Why is the chainstay 15mm longer, with all else being about the same, if that's the case? Just for 40mm tires? What could I expect of it if I put my good wheels on it, and put the ok wheels on my new "third bike", like should I just assume the clumsy was from the tires/wheels and not the long chain stays?
>within 2-3mm or less than 1 degree
Besides doubting this statement a degree in some areas makes a difference between night and day.
Sluggish. But you're saying the wheelbase is within 15 mm of your road bike, the trail is the same (since no one makes odd forks where the rake satisfies '2-3 mm' different from a 45mm fork rake) ? Post botg geos maybe ? One thing that could have ruined the habdling for you is setup. The same bike, or two identical bikes, can behave very different depending on where fit places your center of gravity and how pressure is distributed between front and rear.
>What I'm wondering is, aren't gravel bikes supposed to be all about low speed agility? No, if anything gravel bikes are beyond "endurance" road bikes and are more slack. Some are slacker then old mtb's. cyclocross bikes are the ones (I think) that were designed for slow speed agility, and my ritchey swiss cross seems to fit that realm, but I mostly ride quick vintage road bikes.
>On the one hand balance was piss easy at low speed, but the handlebars were really slow to turn and it felt like tight corners were something of a challenge.
It's easier to balance with more relaxed angles, handlebars are slow to turn because of heavy wheels+tires. Wide bars would help, but "wide" for road users is like 46cm, not 650+ like mtbers run.
>Why is the chainstay 15mm longer, with all else being about the same, if that's the case?
Comfort, tire clearance, less twitchy design focus. Longer chainstays flex more and are inherently more comfortable, while generally required for larger tires. They also improve descending comfort due to reducing twitchiness. This is why DH mtb's are "long and low" for maximum speed.
>Just for 40mm tires? What could I expect of it if I put my good wheels on it, and put the ok wheels on my new "third bike", like should I just assume the clumsy was from the tires/wheels and not the long chain stays?
It will be quicker, but we aren't going to know how much, and how much you can feel.

Maybe ask the bike shop owner if you could do a demo ride with your nice wheels(if everything matches) and off X amount of money before you buy? Admittedly I haven't done much demoing, but I remember a long time ago just riding around the parking lot I noticed how one mtb was way slacker then another, and that wasn't great in the parking lot but now I know it would be better for descending.
"has some scratches and dents", pictures show them all.
I have ridden X miles and it has been fine.

That's what I would do, be open about it.
Sometimes I see frames for sale that are FUCKED, and later on I always see the descriptions added in about the damage. Presumably because someone was interested, asked, and then bailed/low balled.
>What I'm wondering is, aren't gravel bikes supposed to be all about low speed agility?
No. It's mostly marketing. The geometry is all over the fucking place on those. Take anon's advice on another demo with good wheels.

This is the way. Even if the frame is fucked, you might get someone who wants key parts.

One of the most disappointing experiences of my life was a "race" with a bunch of friends at a soapbox derby hill/track.
The rules were, 1: you had to have an assist at the start (someone holding on to your saddle, they release at the signal), 2: no pedalling (fixed was allowed, but you had to have your feet on the downtube).

I was hyped, because I do my own service & my bearings were perfect, and I have good form in a tuck, etc. But the guy who won?

>why hasn't any country rolled it out to their entire fleet?
First of all, there's more than one (way more than one) railway companies operating in each of those countries, especially in freight. Secondly, trains regularly cross boarders too. New systems are hard to get out there because the moment that car is incompatibel with the rest of vehicles out there it can no longer be used for most of its purposes. There's repeatedly been attempts and low-volume implementation, eg. on iron-ore trains in germany that would've been too heavy for buffer-&-chain but ultimately for most applications the advantages are not worth widespread incompatibility as of now.
Ah, cool. Thanks for the explanation. We don't have that type of coupler here, and I was curious about the differences. A shame no one does it correctly, presumably because a guy would have to be between two wagons compressing, which is dangerous? Hopefully these new ones work out better for everyone involved.

Not so much filtered it is a matter of maintenance and cost to own. I would love a Porterfield Flyabout, Fairchild 24 or Curtiss Robin, just the cost to maintain an aircraft with a LeBlond 5, Wright Whirlwind, Curtiss Challenger or Warner Scarab is much more than a Continental, Lycoming or Franklin, and Pratt and Whitney radials are not much better either when it comes to this. If cost is not an issue for a classic, then go ahead, get an aircraft with an inline, V or radial, just know that if you encounter a problem, there is nowhere near the support you get with Continental or Lycoming, where the engines are ubiquitous and considered the industry standard.

A better post-CPL/CFI situation would definitely be a nudge in that direction, and I can imagine that it might be nicer since you've got less people who are just chasing airline paychecks.

The top 2 are the best bikes simply because they are decent in pretty much every kind of situation a cyclist will find himself in.
Capable off road, comfortable and adequate on the road, good for commuting, touring, bike packing, cruising and any other kind of cycling, except track or downhill competition.

Also light enough, durable as hell, reliable, flexible and adaptable, small changes to set up, for example tyres or handlebars, turn them into completely different bikes.

The last few on that list are great at one thing and one thing only, but utter shite at everything else.

80s atb/90s mtb is peak bike.
Nah he's right. Fuck pickups. A van would do your pic better and be more useful day to day. Shit, you could go car camping with a frigging Corolla.
pickups are based in the niche of literally working on a farm but there are 100 times as many dickheads as should shitting up cities with them
The amount of insecure urban chuds driving pickups is absolutely absurd. It's like trying to use a sledgehammer to drive a screw. There's so much downside to driving a friggin land yacht in a dense urban environment, especially one where the average speed is 12mph, there's only one lane for each direction, and public street parking comes at a premium. You have to be the absolute most retarded insecure piece of shit to drive a type of vehicle where half the narrow roads become inaccessible and performing simple maneuvers like turns become not difficult but literally impossible.

A woman who is in a sexual relationship with an aeroplane has revealed that she travelled abroad 30 times in the last year just to spend quality time with her lover.

Sarah Rodo, from Dortmund, Germany, found love on her first flight with a Boeing 737 - after an unfulfilling attempt to date humans.

Since then, the 23-year-old has also 'met' 60 figurines and three larger models who she considers part of a 'collective being' that she is dating, and so she often refers to her lovers as one.

Keeping up a relationship with an object requires real commitment.

The avid jet-setter is so loved up that she has booked 30 mini-breaks in the last 12 months just to be close to her original beau, the Boeing 737.

Despite their many trips together, Sarah, who identifies as objectum sexual [having a sexual or romantic attraction to an inanimate object], is heartbroken that she's never been fully alone with her partner.

Sarah said: 'I'm proud to be objectum sexual – it's a wonderful sexuality, the only sad thing is that I can't be alone with a real plane.

'I flew a lot in the last year to be with the Boeing as often as I possibly could, I took about 30 flights and always combined it with a city trip or vacation.
