Praxis Bottom Bracket for Shimano MTB 73mm BB30/PF30 External Bearings

Brand:Praxis Works

Code:PR-73-3001R

The Praxis Works Shimano Hollowtech II bottom bracket for Mountain Bikes with 73mm Wide Shell 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.

Specifications

Shell Width: 73mm
Shell Fitting: PF30 and BB30 (A Shell adapter is included)
Axle Diameter: 24mm throughout Shimano and similar such as RaceFace (NOT 24mm/22mm as with SRAM and other brands)
Tools Required: Bottom Bracket Press and Shimano Style 16 Notch External Bottom Bracket Tool
