I bent the hanger on my 2013 Response XE. I ordered two different aftermarket replacements. The small screw hole on each of them is about half a mm away from the actual screw hole in the frame. Otherwise they're identical.

The manufacturers of the replacements both say that their spec is for the 2012 model of the bike and may not fit the 2013.

So the question is whether the spec actually changed from 2012 to 2013, or whether both of these aftermarket hangers are defective.
