I picked up this damaged bike today. Obviously the derailleur hanger is bent, and I paid accordingly. (I can't get enough of these damaged dropouts!) Worst case, I could sell a couple parts and recoup my costs, but I'd like to try to repair it if possible. The frame is too large for me, so it will be sold in the end. My first instinct is to put the whole rear dropout/hanger in a vise and then tweak from there. It's obviously got a significant bend, but at least it's still there. I have some concern about preserving the threads, so I'm thinking it may be best to re-bend the hanger with a derailleur mounting bolt still installed. What would you do? Advice welcome.
