Ok so I looked at a couple places for this tube and couldn't find it. A LBC had a 20x1.2, but only in presta. Can't find any on Amazon, ebay, or bicycletires.com.
Am I looking for this correctly? At first, I was strictly searching for 20x1.2, but then read some confusing articles about sizes expressed in fractions not being the same as those expressed in decimals, and the ISO #'s being more accurate.
I guess the question is, for my tire, which has 32x406 and 20x1.2 on the sidewall, which tube is the right one, and where can I buy it?
