RaceFace PF41 CINCH Bottom Bracket

This bottom bracket is designed for PF41 press-fit frames, which covers standards like BB92, BB107, and BB124. It is specifically intended for frames with a 41mm shell diameter that are designed to accept 30mm spindle cranks.

This unit is built for Race Face CINCH cranksets that utilize a 30mm spindle. Ensure your crankset is compatible with the 30mm spindle diameter before installation.

The custom double-row cartridge bearings are engineered to handle higher loads and provide better durability over long-term use. This design helps maintain smooth rotation and longevity, even when riding in demanding trail conditions.

Yes, it includes the necessary inner plastic sleeve to protect against the elements and the appropriate spacers to ensure a versatile, precise fit for your specific frame width.

The integrated inner sleeve acts as a barrier against water, mud, and debris that can enter through the frame. By keeping these contaminants away from the bearings, it significantly extends the lifespan of the component and keeps operation smooth.
