PRAXIS M24 ROAD Bottom Bracket

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.

Be careful not to let your clothing get caught in the chain while riding, otherwise you may fall off the bicycle.
Check that the tension of the chain is correct and that the chain is not damaged. If the tension is too weak or the chain is damaged, the chain should be replaced. The chain may break and you may fall off the bicycle if this is not done.
Use a torque wrench to check the final tightening torque of the main crank bolt and chairing bolts. Furthermore, after riding approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques. Main Crank bolt = Torque 48-55Nm. Chainring Bolts = Torque 8-10Nm.
If the bottom bracket shell is not parallel, shifting performance will be affected and performance will drop.
Check that there are no cracks in the crankarms before riding the bicycle. If there are any cracks, the crankarm may break and you may fall off the bicycle.
Before riding the bicycle, check that there is no play or looseness in the bottom bracket connection. Also, be sure to retighten the crank, chain ring bolts, and pedals at periodic intervals
If you feel any looseness or ‘play’ in the bearings, the bottom bracket should be inspected/replaced.
To ensure the designed performance, only use 10 or 11sp chains by KMC, Shimano, or Campagnolo.
Parts are not guaranteed against natural wear or deterioration resulting from normal use.
For any questions regarding methods of installation, adjustment, maintenance or operation, please contact a professional bicycle dealer or call Praxis Works.
Praxis Works assumes no responsibility for damages or injury related to improperly installed components.
