Standard bicycle bearing ball sizes | BikeGremlin
Apr 13, 2017· Since cups and cones in bicycle bearings have some elasticity and imperfections as well, balls of grade G25 are more than precisely enough machined (round and smooth). Going for higher grade balls (e.g. G10, G5 etc.) will not bring any performance, or durability benefits, just the balls will cost (needlessly) more. 2. Bearing ball hardness
