Do we actually know it was a flat? The twitter video says a bump in the road but honestly it looked like the tyre could have just slid a little and thrown off her balance. That picture she tweeted is grim, looks like the barrier tried to remove her knee cap.
It looks like she was carrying too much speed into the corner, touched a brake and that caused the wobble. She may have punctured subsequently but I don’t think it was the root cause.
I dunno, she had more room still. Looked more like a bump unsettled the bike to me. Maybe she was on the brakes and the bump caused her to overbrake but TT bike brakes aren't ever good enough to buck the bike like that.
