Professional installation by a qualified bicycle technician is recommended due to the need for specific tools and experience.

  • For Conversion BBs: Ensure the black O-ring is on the Non-Drive Cup before pressing it into the Non-Drive side.
  • Apply Anti-Seize to the drive cup threads and smooth taper area before installation.

  • Read the instructions for your front chainrings/crank in conjunction with these service instructions.
  • Do not wash the bottom bracket with high-pressure water jets.
  • For maximum performance, remove, inspect, and clean your Praxis Works bottom bracket periodically.
