M30 Thru T47 Internal Bottom Bracket

Praxis M30 Thru Bottom Bracket

The Praxis M30 Thru BB is engineered 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, increasing rigidity and eliminating common frame and C-clip tolerance issues.

Press-Fit Installation

For press-fit frames, press the longer non-drive cup into the frame, then thread the shorter drive cup in. As the drive cup threads, the collet system expands to a precise limit, evenly distributing pressure for a secure, wiggle-free fit. A compressible O-ring on the non-drive side compensates for frame shell width variations, keeping bearings perfectly aligned.
