PRAXIS Cadet M30 Direct Mount Crankset Instruction Manual
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 these crank service instructions carefully before installing it. Loose, worn or damaged parts may cause riding problems and serious injury may occur as a result. If installation and adjustments are not performed 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 chain tension 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 or else it may break and you may fall off the bicycle.
- Use a torque wrench to check the final tightening torque of the main crank bolt. Furthermore, after riding approximately 60 miles (100 km), use a torque wrench to re-check the tightening torques, including the chainring bolts. Main Crank bolt = Torque 48-52Nm. Chainring Bolts = Torque 8 10Nm.
- If the frame 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, chainring 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, 11 or 12 sp chains (for 12 sp use SRAM Eagle chain only).
- 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.

SIMPLE CRANK REMOVAL
ONLY use an 8mm Allen wrench in the Non-Drive Side crankarm bolt. Turn wrench
counterclockwise to loosen the bolt. After it loosens the resistance will
increase, which is normal, as it is self-extracting. Keep turning to complete
removal of crankarm. Once off, remove the crank from the frame.
