Dura Ace 7900 Bottom Bracket sold separately
The perfect platform for a crank intended to be used at the highest echelon of competition. Combined with a hollow outer chainring the crankset is 20% stiffer for optimal power transfer while still saving 15 grams. Other changes include redesigned chainring teeth for better contact and power transfer. Improved bottom bracket seals further reduce contamination and friction.
