The BB-ES300 Octalink Bottom Bracket is stiff and lightweight for efficient power transfer. It comes with a durable spline reinforced construction and an 8-splined OCTALINK interface. 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 the entire assembly.
- 26 g lighter weight than BB-ES25
- Quick and precise assembly
- Good chain line control with chain stabilizer
