Pretentious French bullshit.
>>2048593They were ahead of their time, they found their use only a century later. No way in hell you're getting a Schrader through a modern deep dish aero wheel.
>>2048594The other day I was standing on line getting a chop cheese at the bodega and this dude by the counter had a clapped out s-works track bike with a zipp service course stem and DT swiss deep dish rims and dura ace spd-sl pedals and some sort of schrader adapter caps on his presta cores and the bar tape looked like it had gone through ww3, I don't know exactly how that worked but it was pretty cool to see a high quality bike being ground to dust by someone who actually used it, good bikes should be ridden hard and frankensteined when they reach a certain age
>>2048601I agree with this shit man theres a certain coolness to kinda ghetto/beat setups that are actually really nice and performance oriented. Like the drift cars of bicyclesIts fucking kino
>>2048593This was invented because the misguided assumption that skinny tires are faster for bike racing.Modern rims are wide enough that you can just drill them out to fit a schrader valve
>schrader valve leaks intensifyPresta got it right by having a valve lock by design
also stem lock>inb4 sheared Schrader valve
Works on my machine
>>2048601Hell yeah
>>2048593Don't care, they just work and you can find pumps for them everywhere.Now those stupid ass dutch thingies however…How did they ever make it out of this fucking lowland hellhole? There's no way to even inflate those fuckers and they have zero improvement over french or car valve, I hate those with a passion.
>>2048645>they just work and you can find pumps for them everywhere.Strange, the only valves giving me constant troubles are these...
>>2048647the only trouble I've gotten from a presta has been related to sealant getting into the valve core and that's easily solved by unscrewing the core, putting a little piece of paper towel on a metal toothpick, and reaming out the rubber crap stuck inside the valve with the paper towel, if you're having issues unrelated to latex sealant there is something wrong with you and not presta
>>2048652>that's easily solved by>a bunch of tedious bullshityeah or you could use a valve that just doesnt have this problem you moron
>>2048615true and it doesn't need a retarded easy to lose cap either
>>2048694schrader has a removable core?
>>2048711Hell yeah, I didn't know either until I decided to put sealant goo in my lawnmowers tires
>>2048711Yes
>laughs in Schwalbe
>>2048615this.Presta is superiour. I even equipped my MTB with Presta valves. Skill issue.
>>2048593to be fair its a less compex valve type.>howeverwhere they connect to the tire is weak, and the most common point of failure.and there is little reason to use a presta valve if your tire is wider than 32 mm.
>>2048613>This was invented becauseis has no preload. As such it opens as soon as pressure outside matches pressure inside. Meanwhile this is not the case obviously for valves with pieces of tube or springs and balls. This may be a entirely academic discussion nowadays but back then when pumps and their seals made fron questionable materials were so-so it may have been a real advantage.>skinny tires are fasterthis is correct.
>>2048837>>skinny tires are faster>this is correct.No they aren't, at least upto a point. Depending on the conditions there's a sweet spot which is quite thick for most conditions.The problem is vibrations slow you down more than the lower rolling resistance from skinny tires.A part of this is better materials and engineering decreased rolling resistance of thicker tires.Ofc this only works upto a point and going all the way to fat tire bike diameters will slow you down again.
>>2049015The sweet spot for normal roads is 30mm by the way.
>>2049021IGN tested this and did find 40mm, ymmv but I'm quite confident that the optimal is higher than most people are used to.
>>2049021You mean 28
>>2049025literally no difference
again:narrower tires are faster.
>>2049065feels > reals
>>2049065good tires are faster. they can be thin, they can be thick, they can even be not slick.
riding monster truck tires on the street in the name of watts is dumb unless you're a hamplanet who measures rides in horizontal rather than vertical distance, I know this is going to enrage the heavies but weight does, in fact, matter. even going from 28 to 32 going uphill feels like you added a drogue chute, I'll put up with the extra weight because it makes high speed descents less stressful but 32 is as high as I go
>OP
>get tpu tubes>they all come with presta for some reason>one leaks like a motherfucker, little pinholes in a dozen spots all over >wanna put some leftover tubeless sealant in so that it fixes itself>non-removable coremotherfuckerswhat's the point of presta if you can't even pull the core out
There’s literally no reason not to use a schrader valve They’re available down to 23 and 25mm width tubes, and it’s is indisputable at this point that there’s no reason to go thinner, like the old 19s And once you’re using tubeless tires like you should because we no longer live in the stone ages it’s even more obvious
>>2051573>like you should because we no longer live in the stone agestubeless is just trading one half-measure (tube) for another (sealant), and tubes are far lower maintenance, especially if you don't cycle the same bike all year. store your summer bike for the winter and come back to globs of sealant pooling on the bottom. and you grab that leftover sealant you had and it's also a solid glob in that bottle. fuck big sealant, keep your toobs.
>>2051563>for some reasonthey want to be able to sell them.>little pinholes in a dozen spots all overthis happened to me at first, the problem was (in my case) the tire bead was so goddamned tight that my normal tire levers were not effective unless they were gouging into the side of the tube. changing to Pedros levers worked for me, at least.
>>2051573on the side of the road changing a flat:>can do the little pre-intlation to get the new tube inside the tire with your mouth in 2 seconds without fumbling with engaging and disengaging the pump for ten strokes.>then uninflate it with your finger.>no valve caps to keep up with.>roll up the old tube and get the remaining air out with your finger on the valve.it ain't much, but less stress the better when you're broke down.
>>2051609>>2051578Okay focus, maybe you like tubes fine, but we’re talking primarily about the valves here, and they should be schrader
>>2051646you don't seem to understand what I wrote.you cannot blow up a schrader tube like a balloon, and you cannot deflate them at will without searching around for a twig or a pen. also, if you don't use a valve cap, mud gets in there, rendering the valve useless. these are pains in the ass when you're trying to change a flat. the superior valve just werks
>>2051670>you can not deflate themdud you have finger(nail)s, right?>>can not blow upyou will need a pump anyways so you have a pumpnot pro Schrader, let alone anti presta. But your arguments are pretty retarded and make almost zero sense.I just wish they made good universal pumpheads. Most of my bikes are presta or regina but I need extra pumps for the other bikes and extra heads or adapters for the floor pumps.Also you all just admit regina valves just mog. It's a shame you hardly find tubes with them anymore. I should start to consider vulcanizing them they're that good.Look good. Always have your valve cap. Even the valve cap looks good. All the advantages of presta. Even better when it comes to security.
>>2048593If European Union had existed 50 years go these would be banned, like all those different bullshit phone chargers connectors 20 years ago got banned.
if these valves are so great why do tyres lose pressure over time
>>2053449Air is very sneaky like Bill Clinton and both have been in and around Epstein island for a long time. Its not the valves that leak so much, its interns.
>>2052839>If European Union had existed 50 years agoIt did though?
