Truvativ Power Spline Bottom Bracket BSA 118mm, 68-73mm

Reliable, robust, and easy to maintain. The Truvativ Power Spline Bottom Bracket is a sealed cartridge bottom bracket designed for use with Truvativ Power Spline splined cranksets — delivering consistent, creak-free performance for mountain bike and road applications.

The BSA English threaded cups install and remove cleanly with a standard bottom bracket tool, and the sealed cartridge bearing assembly keeps moisture and trail debris out of the bearings for long-lasting, low-maintenance performance. The Power Spline splined interface provides a secure, play-free connection between spindle and crank arms for direct, efficient power transfer.

Compatible with both 68mm road and 73mm MTB shell widths in this 118mm spindle length configuration.

Please note: this bottom bracket is designed for Truvativ Power Spline splined cranksets only. It is not compatible with square taper or Isis Drive cranksets. Check your crank compatibility before ordering.
