Now, it all happened in one fell swoop so I'm not entirely sure. But my idea is that as the wheel dropped off the back the chain initially stayed on the cog, then it bent the cog (it's essentially perpendicular to the other cogs now) before the chain finally came off the rear. Oddly, the chain remain glued to the wolf tooth no-drop chainring up front.
Just got the word from the lbs, Specialized will be sending a 2014 stumpjumper marathon carbon my way. So, although I'll have to fork over some pennies for some new components, I don't think I can really complain.
