Hey guys, quick question. I have a 89 Miyata roadie that ive recently put a new BB and crankset in. It had the old square taper and i put a newer style english bracket in it with a RaceFace Cadence crankset that i found at a steal. The problem now is that when i tighten the crank arms all the way up they dont spin freely like they should. I hoped they would loosen up over time but after about 10 miles on it the crank arm just keeps coming loose and im afraid its going to strip out on me. So whats the deal? Is the spindle too short on this particular crankset because the BB is a tad wider on this older bike? Will i have to find another BB or may another crankset? Thanks for any help,

Chris
