The spirit of this board is to compile and organize wheels and tires related discussions.
If a new wheel tech is released, (say for example, TPU tubes, a brand new tire, or a new rim standard), feel free to start the discussion in the popular "Road". Your topic will eventually be moved here!

I'm also amazed nobody has brought up that new SRAM (Zipp) patent in this thread ... the one where they delineate their new idea of GLUEING hooks to hookless rims for tire retention. Which to me is a tacit admission that hookless is both a problem, and is being used because it's cheaper (glue on hooks would lead to fewer QC rejects than molded hooks and thus lower costs).
Retrofit to current Zipp rims which are no longer suitable for 25mm wide tyres according to ETRTO?
Maybe Zipp will be sending out kits with glue.

I'm ok with hooks if it raisses allowed pressure back into "hooked nubmers". Basically telling me that I can do 90psi with 28c tire on 25mm glued-hooked. (Not that I need 90 psi, but still)

Very interesting, and telling, it certainly seems.

For what it's worth, I think it's silly to run a race tire hookless. There's just not enough headroom if you're running higher pressure with a narrow (25 or 28) tire.
That said, I also think it's silly to run anything more narrow than 30 or 32 unless you're racing, unless you don't have clearance. 32's are so incredibly close to the overall performance, I just don't understand running a narrower tire unless you have a number pinned on. And in my opinon, there is absoutely a potential benefit to hookless with a 32: a thicker sidewall that's more impact resistance.
I'm running a pair of cheap Token RoubX wheels; hookess, with 32mm 5000S TR's. I run them at 55-57 PSI, max. There's plenty of headroom, and I have zero worries that they'll come off. The advantage to this set-up is that I can also run them on light gravel with some chunk at about 28 PSI, and the rims still hold up. I do not think a hookless set-up would have held up as well. Impact resistance is absolutely better with a hookless set-up--so those claiming there are "no" advantanges are either misinformed or simply trying to push their own opinion.
If you want to run a narrow tire at high pressure, use a hooked rim. Problem solved.

That's OK. This entire thread, as entertaining and informative as it is, should probably be in the road tire and wheels forum........

People ride for different reasons, at different speeds, on different kinds of roads. It's worth keeping that in mind when saying things like "I think it's silly to run anything [other than what I do]".

65 psi + heavy rider + shitty home pump + hot outside + going fast downhill = who knows what kind of pressure I got there when I'm riding.

ONE HUNDRED PERCENT want conti / extralite to look into his incident and figure out why it happened, improve the product in the future and go from 1 in a thousand to 1 in tens of thousands of incidents if not eliminate completely.
WE ALL KNOW WHAT HAPPENED
but nobody wants to listen
There are variations in tolerances, that's it.And there are no hooks as a backup. Period. No need to investigate.
Y'all are hopeless.
Come back to me when you’ve dealt with your self esteem, anger and superiority complex issues, decided that internet trolling is not a viable hobby and most importantly, grown up to where your mental age matches your physical one.
You're mad because you don't understand how tolerances work, not my problem.
If you follow your thought process to its logical conclusion then we would end up with impossible to meet standards of tolerances, or hooks.
But you're kinda right, there's no reason to post online anymore because people don't listen to me, and all anyone does is bitch about anything that's new or argue especially when they're wrong. It's all whataboutism or bitching about how "you aren't pro" so you don't need to do X and Y. SO BORING!
yeah man. you really need to see someone for your issues mentioned above. This isn't normal behavior. Do you even work in a professional setting? Do you have do deal with other people? Do you have to consider other people's perspectives in your personal or professional life?
All rhetorical ofcourse. You do you bud.

No you're right I'm on the street prostituting for crack and I sleep on a pallet underneath the freeway.
I don't know why you're snowflaking so hard rn about your "perspective" when the discussion is basically about the tolerances of a rim and the tolerances of a tire and what happens when both of them are off in the wrong direction.
But sorry I hurt your feelings so bad.
