Hope they can fix it. I was on a dark shaded trail and don't know if I hit something like a rock or branch, or my limit screw simply worked loose, but in any event, the rear derailler arm moved in too far and snagged the rear wheel spokes and bent the derailler hanger quite badly. It partially pulled the actual "drops" open. Pictures tomorrow.
I'm going to take it down to Urbane Cyclist as they are the local approved BF dealer and have them take a look, but of course it would have to be during "G20" week, when the whole downtown is an armed camp. Luckily the shop is outside the security fence. I may not get there for a day or two depending on my schedule.
I'm guessing if it is too badly bent to straighten out without weakening it, they can either weld a new part on, or even just order a whole new rear triangle, since it simply attaches to the rest of the bike by a hinge.
