The sugino 75 Bottom Bracket is a staple of the Japanese track scene thanks to its high quality machining and mirror polished finish of the bearing races making it an objet d'art as well as go-faster bike component. Intended as the companion of the Sugino 75 crankset. The flip side of running this velodrome thoroughbred is that its weather sealing is pretty much non-existent. Given regular greasing this is fine, but won't take kindly to a fit-and-forget mindset.
