It'll work OK. Given the choice I'd prefer a tube that was slightly undersize over one that's a little too big.

You'll get by with that tube in a pinch, but you'll likely get longer life out of a tube of the proper size.

I used 700x18-25c inner tubes all the time with 28c tires and they were fine. Theoreticaly if you get a puncture the small tubes may deflate faster than a larger one due to it being stretched but I didn't have any paticular problems that I can remmember. Using tubes that are slightly to big will make them very hard to fit and greatly increase the incedence of pinch flats on fitting.

Regards, Anthony

I have had 700x23 tubes for the 27x1.25's on my commuter and I haven't had a problem.

I still have my '86 Cannondale SM700 mtn bike. It has a 26" front wheel & a 24" rear wheel. I always carry a 24" tube so that it will fit both wheels. Always opt for a smaller tube, rather than a larger one. I also carry a 20" tube for my Tour Easy (20" front. 700c rear) and it will "fit" both wheels amazingly enough. Just make sure you have the correct valve type.
The truth is out there!

I bet that's a stretch.

YES, it IS! Back in "the day" the gang at my shop decided to overinflate tubes, just for fun. We once got a 20" tube to almost 7'diameter before failure. So, to decrease "stuff" in the seat pouch, I've only carried small tubes. Works great in pinch.
NOTE; I find most standard innertubes at ACE hardware, $2.19, LBS, about $5.00! You decide!

So have you got any ideas for this one? I have a Terry bike that my granddaughter uses which has a 24 x 1" front tire. 24" inner tubes that are that skinny are hard to find. So far my granddaughter has been successful in avoiding front wheel flats and I've packed along a patch kit just in case. I know the trick about telescoping a larger tube inside of itself to fit a smaller rim but I've never been called upon to try it on a tube this narrow. You have any ideas other than obviously buying the right tube?

I would try a 20x1 1/8 BMX size and stretch that. Should be narrow enough by the time it reaches 24".
Or see if Terry Cycles can set you up w/the correct size. Buy several if you find some, you can always use them in a 700c tire.
NOTE; NO shop will ever recommend this "stretching" technique, but it has always worked for me!
