Praxis Shimano BB30/PF30 Bottom Bracket

The Praxis Works Shimano Hollowtech II bottom bracket converter is designed to be a proper bottom bracket BB for installing Shimano Hollowtech II cranks in either BB30, PF30, or Specialized’s OSBB road frames. High-grade Enduro 2437 bearings are fully sealed and are a fantastic replacement BB for your Shimano™ drivetrain. 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 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 bb converter design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
