CYCLUS TOOLS set: repair cutter and spare repair bush for rear mech hanger threads.
The purpose of the set is to repair the thread inside the rear mech hanger to make it useable again. The repair cutter first removes the old thread and then cuts the new one with a larger diameter.
With the included repair bush then inserted, the frame is repaired and the mech hanger can then be used as before.
Tip: If the damaged thread is in a replaceable type mech hanger, it will be easier to replace the entire hanger part. You will find over 100 different replaceble mech hangers for most popular makes and models in our wholesale product line.
