Newbie - Tube size question(4 posts)

Newbie - Tube size questionECF
Aug 27, 2003 5:29 AM
Hi all,

I've got another newbie question for you. I'm a bigger guy and following some advice I read on this board prior to purchasing my bike I upgraded my rear tire to a 26C from a 23C. The bike is a Specialized Allez Elite 27 with the ALX330 rims that are slightly deeper than standard rims.

On to my question... I see most replacement tubes come in 18-25C or 20-25C sizes. Can I use one of these in a 26C rear tire? Will it cause problems? I'm having trouble finding tubes that specify a range that includes 26C and that have a long valve stem to clear the ALX wheels.

Any advice would be greatly appreciated, as well as any pointers on where to get decent tubes for a decent price.

I would not hesitate.the bull

You will not have any problems.
The tube will expand enough to pump the tire up.
I would go with the bigger size(20-25).
Good luck.

20-25C is fine for your 26. As far as decent tubes, how about your LBS? This is a good litmus test for bike shops, if they don't stock normal inner tubes, find a different shop.
3 bucks for long stem tubes....asphalt assault

My LBS has the long stem presta road tubes that I need but for $7:50...OUCH! I ordered a dozen of these from Webcyclery and they havn't given me any problems as of yet.
