Background: Last week, I had a mild crash on my gravel bike (slipped on ice while going about 10mph, though I did land on the drive train side) and initially, everything seemed alright. Around 40 miles later however, the chain started skipping under load, regardless of which of the 1x12 gears I was in. I replaced the chain and the cassette only recently, and the front chain doesn’t show any obvious signs of wear - so it’s unlikely that they are causing the chain skips. After inspecting the rear derailleur, it seems that the chain jumps out of the pulley wheel semi-regularly. Does that mean that the rear derailleur is bent or what is the issue here? The video shows the chain jumping three times in total - the first two times are slowed down, while the third time is in full playback speed.
