Straightening A Bent Derailleur Hanger

Posted by on in Derailleurs, Frame & Fork


When shifting the rear derailleur up to the biggest cog, the cage was hitting the spokes. The cage seemed to be angled in compared to the cogs. I checked the derailleur hanger with my Park Tool DAG 2.2 Derailleur Alignment Gauge and found it was not straight. I used the tool to straighten the hanger. This fixed the problem.
