bought a vivalo frame that came with a sugino 75 bb. don't know anything about the history of the bike or its setup. the cranks are new. bb lockring is on the non driver side and both bearing cages are tight to bb shell of the frame. is it possible to use some sort of spacer on the drive side and a longer spindle; is this necessary to use a longer spindle? are sugino 75 spiders inset more than other cranks?
