What's the difference between chainwheels/sprockets for 1pc. cranksets vs. 3pc? Can one be converted to another?
I'm upgrading my boy's bike from a 1 pc. to a 3 pc. crankset, so I'd like to know if I can mod his existing chainwheel or do I have to buy a new one?
Sorry for the easy question but I'm an old road bike guy, never have been a BMXer myself.
(edited to correct terminology)
