Fixing a creaky Bottom Bracket

This operation requires specific bike tools, therefore it is best to leave that operation to a bike shop. If you are experiencing a creaky BB, reach out to us on support@analogmotion.com

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)
