I was actually going down hill when the shift was made. I was shifting into a climbing gear when it all happened. My guess is that the slack in the chain maybe created a wave that didn't feed into the rear derailleur and jammed it and the wheel sucked it up into the spokes. The derailleur side of the skewer was ripped out of the frame and it broke off half of the derailleur hanger.
I'm a little worried that it bent the frame at the derailleur hanger and wheel mount. I'll have to check it somehow. Is there a measurement I can make to check this, or is it an "eyeball it" kind of thing?
