Praxis Works Conversion BB (SRAM GXP to BB30/PF30)
This Conversion BB is for installing a Praxis M24 or SRAM GXP steel spindle crank in either BB30 or PF30 road frame. This bottom bracket is made of lightweight and durable aluminum with long lasting sealed cartridge bearings. 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 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.
