i'm trying to change a crank from a 1 piece mongoose that has japan31 and taagi 175 stamped on it, to a tioga cr-mo tubular max-flo 1 piece which has 175x24 stamped on it.
my part of the bb that screws down and holds the sprocket in place wont go on the tioga crank, it starts then wont carry on. obviosly the thread size is different but how do i know which type of bottom bracket i need?
cherrs for looking, joe
