A few weeks ago I had a crash with my Canyon Aeroad, unfortunately landed on the drive side so the majority of the impact was taken by the rear derailleur and the right brifter both got as bit scuffed but nothing major the only part i replaced was the derailleur hanger which cracked. I did get the new derailleur hanger aligned at the local repair shop so I am 100% sure that the hanger is perfectly straight.http://imgur.com/a/Oqxst
Upon further inspection the lower jockey wheel seem to be bent outwards, what makes this a mystery to me is that there are obvious scuff marks on the parallelogram of the RD while the cage has no signs of impact, but then again if the whole derailleur is somehow bent and not just the cage then both the TOP and the bottom jockey wheels would have been out of alignment and the top jockey wheel isn't misaligned which I've visually checked (not sure if it's visible in the photos).
My question is: would it be smart to remove the derailleur and take the cage off to try and bend it back? I'm asking this because there are no signs of shifting problems, what I am worried about though is that somehow the chain will slip off the lower jockey and get stuck which can can cause all sorts of problems.
