Shimano BB-7700 Bottom Bracket 68x109.5mm Dura-Ace

Shimano BB-7700 Bottom bracket with round hollow axle and multi-toothing for the Dura Ace Octalink crankset. Suitable for frames with BSA thread (68mm).

Compared the power transfer of OCTALINK with the conventional square taper spindle, the 8-splined OCTALINK interface that connects bottom bracket and crank set increases the strength and rigidity for entire assembly.
