Crash update.
I finally found some time to clean stuff up, take everything apart, and dig into what may have been damaged. I initially didn't think I bent my derailleur hanger, but I was badly mistaken. My derailleur hanger is quite bent. Which, is a good thing, because I should be able to get another one of those pretty easily and cheaply (though they are currently out of stock at Poseidon).
Bad news, though, is that I do believe the first link of the eGR rear derailleur is also bent. And maybe possibly my frame a tiny bit. I'll bring my bike the LBS this week and see what they think about the frame. Here are the pics of the eGR showing the link, below. Also, my bottom most roller was really, really rough. It looks to be a roller bearing roller and had water and crud in it. I couldn't disassembly it, but I was able to squeeze perhaps the tiniest bit of grease in there and it started to free up a little. Anyone find any replacement rollers that are confirmed to fit?
Does anyone have one not currently on a bike and can please take some similar pictures? It would be nice to compare and see if the little 3-5deg angle in that link is meant to be there, or is the result of my crash.
