Praxis - BB CONV - SRAM/GXP/ISIS2 MTB 73mm BB30/PF30

This Praxis BB converter is designed to be a proper bottom bracket for installing Praxis M24 / SRAM GXP / ISIS2 cranks in either BB30 or PF30 MTB frames. Our patent pending design keeps the cartridge bearings outboard of the frame right on SRAM spec for greater rigidity and free of frame/c-clip tolerance issues that other conversion bb 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 design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
