ABOUT Shimano Bottom Bracket BB-ES300 Octalink BSA (English) Thread
Shimano BB-ES300 Bottom bracket with round hollow axle and multi-toothing for Octalink cranksets. It is suitable for frames with the BSA thread (68mm).
Compared to 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.
