M30 Thru Road 68mm BB30/PF30 R-Collet Bottom Bracket
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.
- For M30 spindle based cranks only.
- Forged & machined heat-treated 7075 T6 Aluminium.
- 30mm Drive & Non-Drive bearing.
- 68mm Road version / 73mm MTB version.
