Dura Ace 7800 Bottom Bracket sold separately

The Dura-Ace 10 speed crankset combines race-proven, hollow-forging technology with an integrated crank set and bottom bracket radically increases efficiency while decreasing weight. Dura-Ace Hollowtech II allows the bottom bracket bearings to be spaced wider apart (outboard bearings) and the axle and bearings themselves to be larger. The net result is a more effective load distribution, increased rigidity and stability and longer service life.
