Sorry to hear about your wreck and I hope you're ok! I would think the wobble was wheel related and not bike related, Cervelo make some of the finest road bikes out there. Obviously from the looks of the front wheel there's no telling now if it failed but you were going pretty fast and possibly ran over something, hit a pot hole, or had unforeseen damage to the rim before your ride to give you the wobble which sent you flying? I've ridden a few bikes with an out of round front wheel and they seem to ride pretty good until the speed increases and then it starts wobbling. The faster you go the worse the wobble. If that was the case then any bike you were on with that wheel would have ended up the same.
