I own a scott sub 20, the tires on the bike state that I need a 28 x 1 3/8 x 1 5/8 innertube. I cannot find these tires anywhere. These are the really thin tires with the presta valve, so I'm assuming they are the 700cc type of tires. Unfortunately, I cannot figure out how to convert the numbers.
What do these numbers convert to?
What conversion rate/formula should I be using to figure out the proper size innertubes I need?
