Praxis M30 Thru Bottom Bracket

The Praxis M30 Thru BB is designed for installing Praxis Lyft Carbon, RaceFace Cinch, Rotor REX MTB, or CaneCreek eeWings cranks. Its patent-pending outboard bearing design positions the Enduro 6806 cartridge bearings outside the frame for greater rigidity and eliminates tolerance issues common with other bottom bracket systems.

Press-Fit Installation

• Press the longer non-drive cup into the frame.

• Thread in the shorter drive cup. As it threads, the collet system expands to a precise limit, evenly dispersing pressure for a secure, wiggle-free fit.

• A compressible O-ring on the non-drive side compensates for frame shell width differences.

• Compatible with BB30, PF30, BB86, BB90, and BB92 frames. BB92 guide is required for BB92 frames.
