Unlock the potential of your BB30 or Pressfit 30 (PF30) frame with Praxis' conversion bottom bracket—a robust platform for your preferred cranks. Its threaded design, unique in the market, ensures a secure interface. The press-fit non-drive side and threaded drive side cup, tightened with a Shimano BB tool, create a solid friction hold, preventing any wobbling under load. This innovative design eliminates creaks associated with pressfit BBs.
OSBB
With two offerings a Praxis conversion can be used to convert your Specialized OSBB frame to either a Shimano HTII (24 mm spindle) or a M24 / GXP (24 mm / 22 mm spindle) bottom bracket.

The conversion bottom bracket's shape accommodates nearly any wire over the BB shell in most frames. The shell holes are for weight savings, not wire routing. If used as a last resort, ensure wiring is protected from the spinning axle.
