Yo, how many of you would use these tubes?
I posted this here because I was thinking about how we have to go though the trouble of removing the rear wheel and messing with chain tension when all the work is done. Now, if these tubes actually do a good job, all that is pretty much done with.
If only they were with Presta valves.

Certainly would be a cleaner tube swap…but it's not really that much of a hassle to take the wheel off and adjust chain tension. I've changed a rear tube during a race in under 5 minutes. That is an awesome idea though. If they weren't any more expensive than what I normally get (you know, proper size with presta valves with removable valve cores) I would surely give 'em a try. I don't think I'd pay any more for them though.

I know it's not a huge hassle, but there have been days where I forgot my wrench at home.

and you're probably better off getting a Hutchinson Road Tubeless kit from Stan's than going about this route. With the extra weight of a Deep-V you need to shed some weight at the rim anyway.

Trying to replace a tube without removing the wheel sounds fantastically frustrating...
Can you imagine trying to hook the end of the tube over the valve with the tire in place?

Somebody still makes these?
Specialized tried out this idea about 10 yrs ago, called it the "dirt worm". The idea was faster tube changes during a race and, Suprise! They were more of a hassle than removing the wheel.....I think they only sold them for one year.

I think it's more geared for the fellows who have standard bolts (nuts?) instead of QR. I could see it being easier then carrying around a wrench or whatnot. But meh.

It's not that bad. Sometimes if I have a rear flat, rather than removing the wheel I'll remove one bead of the tire, pull the tube to the side, find the hole, patch it, and reinstall the tube and tire. This is with full fenders and a rack with a wide pannier support area.
