M30 Thru T47 External Bottom Bracket

Praxis M30 Bottom Bracket Converter – BB30 / PF30 MTB

The Praxis Works M30 bottom bracket converter allows installation of Praxis M30 cranks (30/28mm stepped spindle) into BB30 or PF30 MTB frames. High-grade Enduro 2437 sealed cartridge bearings deliver 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 found in other conversion bottom brackets.
