Shimano's sleek redesign for the Ultegra 6800 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 6800 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.
