Troubleshooting
Derailleur does not shift to the largest chainring.
Check if the outer limit screw is set too far in. Adjust the outer limit screw to allow more movement outward. Ensure the chainring size does not exceed 40 teeth.
Chain rubs on the derailleur cage in certain gears.
Adjust the derailleur's cable tension. If rubbing on the inside, increase tension slightly. If rubbing on the outside, decrease tension slightly. Verify the chainstay angle compatibility.
Shifting is slow or hesitant.
Clean and lubricate the derailleur's moving parts and shift cable. Check for any kinks or damage in the shifter cable and housing.
Derailleur cage interferes with frame.
Ensure the correct frame tube diameter clamp size is being used. Verify that the chainstay to seat tube angle is within the 66-69 degree range.
