Tube Question

[KnottedYet]

I was under the impression that was the correct size. Tires come in gradations of every two mm or so, and tubes are in larger gradations. You get the tube with the range that suits the specific tire width.

(kinda like jeans come in sizes 2,4,6,8,10,12,14,16,18, etc and underwear comes in S,M,L,XL)

I love my LBS, cuz they are willing to explain everything to me, even when all I'm doing is buying a tube!

The tire was 35c, the tube was 29-32c. That is not in the range of the tire. That is why I was wondering why it seems to be normal to put a smaller tubes in larger tires.

Oh, got it now. Sorry.

Looking at some available tubes, there are 28-32 and 35-38 by Performance and 20-28 and 28-38 by Specialized, 25-32 and 35-40 by Michelin. So 34 is in between sizes in some brands. The guys at my LBS keep trying to get Specialized to change the labeling on their tubes because they use the 20-28s up to 32 (or something like that). Anyway, tubes are very stretchy and just expand to fill the tire volume, so the stated widths aren't exact. Better to use a tube labeled for a smaller tire than one labeled for a larger tire if your tire is in the middle.
