  • Before installing a new derailleur hanger, check the state of dropout. 
  • If the area you seem damaged, do not install new hanger and go to a professional mechanic who will analyze the state of the frame.
  • If the state of the area you seem okay, then clean and apply a light film of grease to minimize noise or “creaking.”
  • Apply Loctite on the screws and mount the bracket into place by tightening the screws reasonably (warning: overtightening can damage the threads of the hanger).
  • Check to make sure that the hanger screw ends do not contact or interfere with the rear sprocket or chain. File the protruding screw end if necessary..
  • Re-attach the rear derailleur and check derailleur alignment using the following diagram. If, with a new hanger you don't get an alignment at 90 °, don't get a new hanger and go to a professional mechanic who will analyze the state of the frame.
