BSA 30mm Bottom Bracket w/ AC Bearings

This is Wheels Manufacturing's solution for running a 30mm spindle crankset in a BSA threaded frame. Machined aluminum cups thread in to a standard threaded frame and feature Enduro 6806 Angular Contact sealed bearings outboard of the BB shell. Fully serviceable.

For use with 30mm diameter cranks with a spindle length of at least 104mm when used in a 68mm wide BB shell. This is the overall spindle length with all spacers and adjusters removed from the spindle. Measurement is taken from the inside face of the crank arm to the very end of the spindle.

WILL NOT work with standard BB30 cranksets. PLEASE MEASURE YOUR BB30 CRANK SPINDLE LENGTH!

  • Angular contact bearings have a much higher speed rating than radial bearings because of the nonstop contact of the balls to both rings. Angular contact bearings can carry both radial and axial loads. The weight of the load is transferred from one ring to the other, through the balls, along a specific contact angle.
