Haha nothing happened to it. The drive side down bar that is bent is done intentionally by the manufacturer. Just part of the engineering behind this particular frame design. Try to find another '06 or '05 7point rear triangle shot, and you'll see what I'm saying. Also, the tire doesnt come close to rubbing, the depth perception of this photo just makes it look that way.

 Dude what happened to that rear triangle? Are you selling this thing with tire rub?

 that was my old bike ahaha holy shit thats so weird. i sold it to some other due in orgeon

 its a pretty small community here and an even smaller one when your into a sport such as this
