The TruVativ Powerspline bottom bracket was designed by SRAM for use with a few of their popular cranksets. Offering more contact points than the traditional square taper bottom bracket, the TruVativ Powerspline BB features a 12 splined tapered spindle that's heat treated for stiffness and durability.
Recommended for use with the SRAM S100 Courier Crankset.
