    Praxis Works Praxis BB30-PF30 Bottom Bracket For Sram GXP-ISIS2

    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. Features TECHNOLOGY Patent Pending Outboard Bearing Design. “Collet” style non-drive cup expansion for wiggle-free press. Non-Drive O-Ring compensates for frame width discrepancies. VIP NOTES Not for BBRight or BB386EVO frames. 68mm cannot be used for MTB Cranks. MTB Guides - ISCG05 Good, ST Mounted Good, ISCG03 Not Good. WARRANTY Praxis Works warrants components to be free from defects in materials or workmanship for a period of 2 years after original purchase. However, there are limitations as “nothing lasts forever” so please read our Warranty Page Specification For SRAM GXP/ISIS2 cranks. Also for Oval Concepts 400/500/700 series GXP cranks. Forged & machined heat-treated 7075 T6 Aluminium. Steel cartridge radial bearings. 68mm Road version. For BB30, PF30, and Specialized Road OSBB. INSTRUCTIONS HERE Find out more...
