....ahhh, well, they HAVE been around for a few years and are all the rage for the very reason you point out. It just goes to show you have to be quick with your million dollar idea!

I think there was a tubular mountain bike tire / rim a while ago (maybe 10 or 15 years back). I can't remember for the life of me who made it, but it never caught on, obvioiusly.

I guess to be fair they really aren't "tubular" they are "tubeless."

tubeless MTB tires is the new thing to eliminate pinch flats.

Tubular glue mixed with the grime of Mtn. Biking...probably lead to too many flats... ;)

gary fisher had a sew-up mtn bike tire. now THAT one, we could talk about pinch flats with. :) it ran into . . . . . . . . . a few . . . . . . .. . problems in real life that gary didn't think about while sketching it out on that cocktail napkin.

very stupid idea. remember "freeclimb bikes", and the evo headset ??? :) gotta love gary.

i wish i had a set of those mtn bike sew-ups to sell on ebay, tho . . . .

Yes, but the tubeless MTB tires have NONE of the said advantages of tubulars (better ride, lower rotational wt., etc.) except for a slight improvement of pinch-flat resistance.

.....but I'd still tell t-t-n they feel faster (even though I haven't tried them because they haven't met my value threashold).

oh, you were serious!

the sew-up mtn tire would roll off the rim, for one thing. it was large, and ran at low pressure. much of what keeps raos tires on is simply pressure and fit, and the fact that the tire is not too tall or big and so doesn't TRY to roll off all that much.

it slipped.

it tore the cloth backing off.

the whole spare issue !!!

cost. and, repair time from the cuts and thorns and whatnot that it got anyway.

rocks in the glue.

the fact that a spare on the rim not properly glued had all the above problems times 4 or five and now you had to ride home on it.

etc etc. bad idea. one of the worst, ever. :)

an exception: Stan's tubeless system are the only tubeless MTB tires worth anything, but they still appear to be inferior to a true TUBULAR MTB tire system, if you think that the tubular advantage would carry over to MTB.
