Just don’t puncture the central rib…

I’m ready with the snark and cynicism but i’m intrigued. Someone else please do the mocking.
I like how he says tyre though, that must count for something.

New word for the day… circumferentially !!!

just think of the possibilities. An All Mountain tyre that you can flip round to inflate on the climbs and deflate on the downs, think of the radness that that could cause. Imagine how long you could faff with that for! Imagine!

I actually thinks its cool for your “just a bike” bike

so how do you stop it inflating (watched video with sound down so may have missed summit)

New word for the day… circumferentially !!!

Yeah, thought this too lol.

Apparently it stops when it reaches a certain pressure mark. Sounds a bit dubious, you would need different types of tyre for different weight riders..

Love the idea, and it looks like it works, and it’s great. Just not really a real life application IMO.

Great idea! But can’t see the application.

I’d comment, but anything I said would just be a rehash of BSNYC’s comments on it, so you might as well read the original (scroll down a bit to just below the bike with the steering wheel):

bump for the day shift

what about in the rain or deep puddles would it fill up with water?
