Hello,
My rear wheel from my road bike was stolen a month back, I replaced the wheel but the cassette on the new wheel only had 6 gears instead of 7. I thought I adjusted the guide-screws enough to get by and avoid overshoot but today, in the middle of a long ride, my chain went over the lowest rear gear and my derailleur hanger got caught in the spokes. I wasn't going that fast when it happened (I had just gone over a curb and was starting to accelerate), but there was enough force to break off the bottom jockey wheel and the inner detachable part of the hanger is probably shot. So a decent amount of force, it seems. As it stands, the main part of the derailleur is definitely way out of alignment, perhaps 10 or even 15 degrees, hard to tell exactly. The derailleur's a complicated piece and I'm not a great mechanic, so I can't tell exactly where it bent/broke (or to what extent), thus I'm not sure if it can just be bent back by a good mechanic or whether I've damaged the main derailleur parts.
Anybody have any experience with this? I live in Russia in and don't have a good mechanic I trust here (plus the language barrier), so I'd like an idea of how bad it is before I see anyone. Also, I'm going to Germany in a couple days and could buy a replacement derailleur there, whereas here I might need to order it and it could take a long time to arrive - nobody drives road bikes here.
Also, the dropout on the frame looks okay from what I can tell, but I'm not 100% sure it couldn't have gotten a bit bent as well. I mean, that would mean a LOT of force being transferred through the derailleur, so I think it's very unlikely. Any thoughts on this?
