The Praxis Conversion Bottom Bracket is the ideal solution for cyclists looking to install a GXP crankset onto a BB30, PF30, or Specialized OSBB road bike frame. Designed for those seeking a reliable and creak-free interface, it allows for seamless component mixing, though users must carefully manage the included plastic sleeve depending on their specific bottom bracket shell type.

No, this specific model is optimized for 68mm road frames. For 73mm shells, please refer to the Praxis 73mm variant.
No, the plastic sleeve should be removed when installing this kit into a standard BB30 shell.
No, this conversion kit is specifically engineered for SRAM GXP cranksets.
Service intervals depend on riding conditions, but the bearings should be inspected for smoothness at least once per season or after significant wet-weather riding.
Yes, it is designed to be compatible with Specialized OSBB frames.
Remove the bottom bracket, clean the shell thoroughly, apply fresh high-quality grease, and ensure it is pressed in perfectly square.
Verify that the correct GXP-specific spacers are being used and that the non-drive side pinch bolt is torqued to the manufacturer's specification.
Ensure the frame shell is clean of any paint or debris and use a proper bearing press tool; never strike the bearing directly with a hammer.
Installation requires professional-grade press tools to ensure the bearings are seated perfectly square within the frame. Compatibility is strictly limited to 68mm shell widths. For BB30 installations, remove the internal plastic sleeve before pressing the cups into the frame. For PF30 installations, you must keep the sleeve installed to act as a spacer and guide. Always use high-quality, bike-specific waterproof grease on all interfaces during installation to prevent oxidation and ensure ease of future removal. Avoid using high-pressure water sprayers directly on the bottom bracket area during cleaning to maintain internal bearing grease integrity.
