69ers and spare inner tubes?

gregsd

Well, just picked up my new Trek 69er and wonder what other riders do regarding spare tube on rides. Do you take both tubes just in case or can you make a 26" tube work on the 29r wheel, just to get you home?

:oops:

Surely it would be better to take a 29inch inner tube ?

Yes it will fit you only need an extra 10" so it will get you out of trouble.

A 29er tube will work in a 26" wheel at a push.

It won't be particularly nice though. Emergency only I'd say.

I reckon your better with a 26 tube inside the 29 than vice versa, bunching up an oversize tube is a recipe for the tube getting pinched by the bead or creased and rubbing thorugh itself.

A Friend has a 36er and uses 29er tubes in that (as 36er tubes weigh nearly 1Kg!)
