Middleburn Breakaway Derailleur Bolt
Breakaway bolts are derailleur mount bolts designed for frames that don't have a replaceable mech hanger. Designed to break before the mech hanger on your frame.
Fit all pre-Shadow Shimano derailleurs
Middleburn say :-
Breakaway bolts are specially weakened derailleur pivot bolts that are designed to "break away" when a severe impact occurs. Much better to break a small bolt than to strip the threads out of your expensive frame, we think you'll agree! Lightweight too.
