Sugino 75 bottom bracket, using CERAMIC ball bearings. Definitely smoother than butter.  This may not be NJS certified, but may be used in pro-racing outside of Japan. Suitable to use with cranks such as Sugino Grand Mighty and Sugino 75.

Sugino has revised their products and their Sugino 75 crankarms are now using a proprietary tapered crank arm and hence, it is important to match your Sugino 75 cranks with Sugino 75 BBs else warranty will be voided!

• Mirror Polished Bearing Races
• Crank bolts are included.
