Praxis M30 Bottom Bracket

The Praxis M30 bottom bracket provides a solid platform for the Zayante crankset. Its stepped 30 to 28mm spindle perfectly matches the crank's design for optimal power transfer and efficiency. Praxis' innovative "wide stance" technology pushes the cartridge bearings outward, moving your feet's pedaling forces further from the frame. This creates rock-solid pedaling stability while avoiding problematic frame tolerances. Currently available for most major bottom bracket standards, the M30 bottom bracket delivers Praxis' signature quiet performance and long service life through thoughtful engineering. Riders trust Praxis for bottom brackets engineered for their cranksets.

Praxis M30 threaded bottom brackets require the M30 BB Tool to be correctly installed. The T47 Internal requires the T47 I.B tool, while any press-fit versions should be installed using a good quality bearing press. The T47 Asym uses both. Compatibility is listed below.
