Praxis M30 Threaded BB

M30 Press Fit BB
This is our M30 Press Fit Bottom Bracket for installing a Praxis M30 crank into a 68mm/73mm BB30 or PF30 frame. Our patent pending design keeps the cartridge bearings outboard of the frame right on Shimano™ spec for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with.

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