I can't be sure. It was a friend's bike, and I was used to mountain bikes, not racing bikes.
I may have been leaning forward, I may have jammed the wrong brake. The bike may have had any of the problems you list. That combined with the manhole + hill speed was probably what did it.
I now use the public bike system in Montreal, bixi. Very convenient, and they're built like tanks, so I feel confident it won't happen again.
