There is a noise coming from the cranks, pedals or bottom bracket of my AMX
If you are experiencing noise coming from the cranks, pedals or bottom bracket of an AMX it is important to find the source.
The most common reasons can be resolved below:
- Pedal assembly - Ensure your pedals were installed correctly and fully tightened (see here).
- Crank arm assembly - Ensure your crank arm is fully tight. Use an 8mm Hex Key to tighten the left and right crank arm bolt.
If the noise persists, it could be a known issue due to the Bottom Bracket being not torqued properly. If you have any concerns, reach out to us on firstname.lastname@example.org and we can assist you accordingly.
Fixing a creaky Bottom Bracket
1. Remove the left crank arm
Use an 8mm Hex Key to remove the left crank arm bolt.
Use a crankset extractor tool (we use the Park Tool CCP-22 in this guide) to remove the crank arm on the left side.
2. Tighten the bottom bracket left cup to 35nm
Use a Torque Wrench and a Bottom Bracket Removal Tool to tight the shell to 35Nm.
Once you've torqued the cup properly, you can place the crank arm back. Slide it onto the BB axle and use the 8mm hex key to tighten the bolt (recommended torque is 50nm)
