Hmm, good question.
As best as I can remember (from witnesess statements), since I was standing and mashing hard, when the bike STOPPED, I kept going. Since I was standing, (and doing a rather good clip) that means I was launched forward. Also from the damage to my bar tape, the front wheel also appears to have turned sideways. I can only guess that it did so violently. I'm also not sure at what point my SPDs disengaged either. But since I was some distance from the bike, I know they did.
This is only speculation, since I can't remember the actual event. I have to rely on the witnesses.
I don't think it takes a Physics Professor to figure it out.
