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. 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. • For Shimano Hollowtech II cranks. • Forged & machined heat-treated 7075 T6 Aluminium. • Steel cartridge radial bearings. • 73mm MTB Version. • For BB30, PF30.
