i feel kinda stupid to ask this question, so please donīt chair me if you do think so.
on the LHT page, surly site, it says, maximum chainring clearance: 38/52/56t
whatīs the difference? i mean, is 38 bigger than 22, or what? and whatīs the guideline to determine the, i donīt know how to call it, dimension of the chainring?
