Praxis Works BB30/PF30 SRAM GXP MTB Bottom Bracket 73 mm
SRAM GXP/ISIS2 Converter The Praxis Works SRAM bottom bracket converter GXP/ISIS 2 is designed to be a proper bottom bracket BB for installing SRAM GXP/ISIS2 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 SRAM 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 design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies. Patent Pending Outboard Bearing Design. “Collet” style non-drive cup expansion for wiggle-free press. Non-Drive O-Ring compensates for frame width discrepancies. For BB30, PF30, and Specialized Road OSBB frames only. For SRAM GXP/ISIS2 cranks.
