- 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.
- Tool Pattern: 44mm, 16-notch
Thread together bottom bracket for frames using the PF30 bottom bracket standard. Two machined aluminum cups thread together keeping the bottom bracket stable in the frame, increasing bearing life, and simplifying maintenance. This means no more creaking, smoother operation, longer bearing life, and really quick bearing replacement.
Specifically designed for installing 22mm / 24mm spindle diameter cranks (SRAM / Truvativ GXP) in PF30 (46mm ID BB shell) frames without the need for any adapters.
