Praxis Campagnolo BB30, PF30 or OSBB Conversion
Designed as a proper bottom bracket BB for installing Campagnolo Ultra Torque cranks in either BB30, PF30, or Specialized’s OSBB frames. Our patent pending design keeps the bearings outboard of the frame right on Campagnolo 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.
