SAFETY INFORMATION – READ BEFORE RIDE

Since specific tools and experience are necessary for proper installation, it is recommended that the product be installed by a qualified bicycle technician.
Read the service instructions of your crank carefully prior to installing the parts. Loose, worn or damaged parts may cause riding problems and serious injury may occur as a result. If installation and adjustments are not carried out correctly, the chain may come off and this may cause you to fall off the bicycle which could result in serious injury. Read these instructions carefully, and keep them for later use.

  • Ensure that your BB30/PF30 frame shell is clean. If a BB30 frame, remove the c-clips/bearings so frame shell is empty.
  • Conversion BB – Make sure the black O-ring is on the Non-Drive Cup prior to pressing into Non-Drive side.
  • Apply Anti-Seize to the drive cup threads and smooth taper area before installing.
  • Before riding the bicycle, check that there is no play or looseness in the bottom bracket connection. Also, be sure to retighten the crankarms and pedals at periodic intervals.
  • If you feel any looseness or ‘play’ in the bearings, the bottom bracket should be inspected/replaced.
  • Be sure to read the instructions for your front chainrings/crank in conjunction with these service instructions.
  • Do not wash the bottom bracket with high-pressure jets of water.
  • For maximum performance it is required to remove and periodically inspect/clean your Praxis Works bottom bracket.
