FSA BSA PowerDrive Bottom Bracket

Proven, reliable, and built to last. The FSA BSA PowerDrive Bottom Bracket is a high-quality threaded cartridge bottom bracket designed specifically for FSA PowerDrive splined cranksets — delivering smooth, efficient power transfer for road and mountain bike applications.

The forged hollow SCM4130 chromoly steel spindle is exceptionally strong and stiff, handling the high torque loads of hard riding without flex or fatigue. Industrial 6002KRS sealed cartridge bearings with oversized 3/16" diameter ball bearings provide smooth rotation and excellent resistance to contamination, reducing the need for frequent maintenance and keeping your drivetrain running quietly for the long haul.

BSA English threaded cups ensure easy installation and removal with a standard bottom bracket tool, and the unit is compatible with both 68mm road and 73mm MTB shell widths. Available in three spindle lengths to suit your specific crankset and frame combination.

Please note: this bottom bracket is designed for FSA PowerDrive splined cranksets and is not compatible with square taper cranksets. Check your crank compatibility before ordering.
