I was suffering bad shifting and skips and my derailleur appeared to be bent slightly inwards, so I thought I’d check it with a Park DAG 2.2 I already owned (for a previous bike).
Instead of the hanger I expected it looks like I’ve got a “direct mount”? I haven’t come across this before, the derailleur is attached to this black piece (bracket axle?) with the smaller bolt I’m holding - not M10.
Can it still be aligned with Park DAG? Should I be trying to bend the black piece (in which case, do I need some kind of adapter to fit the smaller thread), or the hanging bit of frame?
