Safety Information

READ BEFORE RIDE

Installation requires specific tools and experience. 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. If installation and adjustments are not carried out correctly, the chain may come off, potentially causing a fall and serious injury. Read these instructions carefully and keep them for later use.

• Before installing the new BB, ensure the frame shell is clean and empty of all parts.
• Before riding, check for any play or looseness in the bottom bracket connection. Retighten crankarms and pedals at periodic intervals.
• If looseness or 'play' is felt in the bearings, the bottom bracket should be inspected or replaced.
• 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, remove and periodically inspect/clean your Praxis Works bottom bracket.
• Parts are not guaranteed against natural wear or deterioration resulting from normal use.
• For questions regarding installation, adjustment, maintenance, or operation, contact a professional bicycle dealer or Praxis Works.
• Praxis Works assumes no responsibility for damages or injury related to improperly installed components.
