BB-ES51 Bottom bracket with round hollow axle and multi-toothing for Octalink cranksets. Suitable for frames with BSA thread (73mm).
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.
