Praxis M30 Press Fit bottom brackets are designed to be a proper bottom bracket (BB) for installing Turn M30 spindle based cranks in either; _x000D__x000D_ • BB30 _x000D_ • PF30 _x000D_ • BB86 _x000D_ • BB92 _x000D_ • Specialized’s OSBB frames. _x000D_ _x000D_ 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._x000D_ _x000D_ 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.
