BSA Bottom Bracket

The Wolf Tooth BSA Bottom Bracket addresses the root cause of drivetrain creaking rather than just tolerating it. Custom polymer spindle bushings isolate the bearing inner race from the crank spindle, and the six-layer sealing stack keeps that interface clean through wet, muddy trail and enduro miles. When the bearings eventually wear, Wolf Tooth's Right to Repair policy keeps replacement parts available so the shell stays in service.

What Our Gearhead® Experts Are Saying:

"The polymer spindle bushings are what actually solve creaking. They keep the bearing inner race from contacting the crank spindle directly, which is where that noise starts in the first place."
