Praxis BB M30 THRU T47 External

M30 Thru BB

The Praxis M30 Thru BB is designed to be a proper bottom bracket (BB) for installing the Praxis Lyft Carbon Crank, RaceFace "Cinch", Rotor “REX” MTB Crank or CaneCreek eeWings. The Praxis patent pending design keeps the Enduro 6806 cartridge bearings outboard of the frame for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with.

For Press Fit Options...

Simply press in the longer non-drive-cup, then thread the shorter Drive cup into it. As the drive cup threads in, the trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and the collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
