has anyone ever seen a 29" latex tube, or has anyone used a 26" tube and stretched it? i am interested in using this setup in a racing only situation for lightness and pinchflat resistance so air loss should not be a big issue.

Challenge make some that are 700x 30/35, but I'm not sure if they'll strech enough to fit a 45/50mm tire. They are pretty thin to start with.

i was aware of those. i plan on running them in a 29x2.1. wasn't sure if it would be a better idea to stretch a 26x2.1 or a 700x35?

Just out of curiosity, Why is tubeless not an option?

On another note I have successfully run 26" latex tubes in my 29er before, albeit for hill-climb application only.

not ready to put out the cash for a tubeless set up. im sure i would like to go tubeless some day but right now right now. i have a superlight set of rim brake wheels now. i think my set up is lighter than a tubeless disc set-up, but that is another whole discussion.

I use 26" Latex Michelins in my 29" tires all the time. Have you ever pumped up a latex inner tube outside of the tire? It gets really big... The 26"->29" stretch is a piece of cake for these tubes. Don't worry.

I'd rather use a 26" latex tube than a stretched 700x35 tube. The latter would get very thin walls, the first would not.

I've used Michelin Latex 26" tubes in 29er wheels before, never had a problem.

Only problem I've found so far is that the 26" latex tubes can be a little difficult to mount. If you want to change a tube e.g. during a race it will take a little longer to put in a 26" tube than a 29" tube...

Gotta train on that a bit. I start opposite of the valve hole and use a foot to hold the tube in the tire, while I work the tube in on both halves of the wheel.

No reason to use heavy 29er specific tubes or 700c latex tubes that are too thin to be safe. Just use 26" latex.

36mm or 42mm refers to valve length I believe, not width.

you're right, the difference is the valve model, diff in valve length is only 2mm

Convert your existing wheels to tubeless. No need to buy new wheels.
