Bike tube sizing
#1
Hi all. I have a 1993 Nishiki Modulus I use to commute to university classes, except right now I have a flat in the back tire. The tube on the back tire says its size is 27"x1" 90-110 psi, but all the tubes I can find online are x1 1/8" or x1 1/4". Am I missing something about road bike widths here? Will that extra eighth or quarter of an inch mean the tube won't fit, or can I get by with it? If not, where can I find a tube to fit my rim?

Apologies if this question has been answered previously, I only had a quick look around before I asked.

Cheers,

D

A 27 x 1 1/8 should be fine. Avoid ones that only list 1 1/4 as the size. They may work, but may be too big. It depends on the brand.

May be better to get something listed as a 700 x 23-25. Those will work and they'll be narrower than the 27 x 1 1/8 tubes and will still work fine.

Make sure to get the right valve type (presta or schraeder)

You can also get a patch kit at just about any bike, sports or big box store.
Make sure to check the tire to make sure whatever popped it isn't still lodged in the tire.
