Praxis M30 Thru Bottom Bracket

The Praxis M30 Thru BB is engineered for 30mm spindle cranks, including Lyft Carbon and Doon Carbon cranks, as well as compatible models from SRAM, RaceFace/Easton Cinch, Rotor Rex/3D+, and Cane Creek eeWings. 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.
