Lighter and faster
Shimano’s sleek redesign for the Ultegra SM-BBR60 Bottom Bracket is lighter and faster than before, making it the ideal choice for either your English- or Italian-threaded frame. The new SM-BBR60 is close to 15 grams lighter than its predecessor, and the new design has reduced rotational friction by roughly 50%. This new silky-smooth ride is courtesy of steel bearings and Shimano’s advanced sealing technologies.
