Praxis M30 Bottom Bracket Converter – BB30 / PF30 / OSBB Road

The Praxis Works M30 bottom bracket converter allows installation of Praxis M30 cranks (30/28mm stepped spindle) into BB30, PF30, or Specialized OSBB road frames. High-grade Enduro 2437 sealed cartridge bearings provide smooth performance and long service life. The patent-pending outboard bearing design positions the bearings outside the frame for increased rigidity and eliminates tolerance issues commonly found in other conversion bottom brackets.
