Troubleshooting
Derailleur feels loose after installation
Ensure the retention bolt is tightened to the correct torque specification. Check that the bolt and hanger threads are clean and free of debris. Verify compatibility with your specific derailleur system.
Shifting performance is inconsistent
A loose derailleur bolt can cause shifting issues. Re-check the tightness of the retention bolt. Ensure the derailleur itself is properly aligned and not damaged. Confirm you are using a compatible derailleur with the retention bolt.
Bolt threads are damaged or stripped
Stop installation immediately. Inspect both the bolt and the hanger threads. If threads are damaged, the hanger or bolt may need replacement. Cleanliness during installation prevents thread damage.
