In a recent post, a gentleman described a bad accident that happened after his chain derailed. Apparently he was pedaling hard uphill when the chain came off the ring and he was hurled over the bars. Did this happen because all the force that he was applying to the drive train suddenly stop and it had to go somewhere else - in this case into forward motion to propel him over the bars? I'm trying to understand why this derailment resulted in such a bad accident.
I've only had one chain break and I was on a flat surface going only 8-10 mph so I experienced no loss of control - just couldn't pedal anymore.
