Agree with Clifford. The pulley has a sleeve bushing that is wider then the plastic pulley and a thin dust cap on both sides. Unless the dust caps are deformed or the sleeve is wrong/missing the bolt can be tightened to a fairly high level and not effect the pulley's spin. BTW campy pulleys like to be lubed. Andy.
