Praxis Works Bottom Bracket Converter SRAM

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.

• 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

The Praxis 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, the Praxis trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and the 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.
