Best wishes of a speedy recovery from me too
Agree with Vamp: It sounds like the chain shipped at the front, that would potentially jam the cranks instantly, what happened at the back is just the result of the accident.
What speed were you doing when it jammed?
And I have no wish to know how painful a broken femur is.
I think thats an RD-C600 which is reverse sprung. Techdocs sugest that it indexed from large cog hence pulling in.
When I broke my femur my RHR went up from c.50 to c.70, and stayed there for months. Even when I came off the painkillers, it remained high. I assumed that it was caused by the body working harder than usual to heal itself. It's only in the last few weeks (6 months and 1,000 miles of riding post-accident) that it's gone down to normal levels.Also, my resting heart rate is now constantly around 80-90, whereas before it was usually around 42-45. The accident was only a week ago, so I won't have lost that much fitness yet...presumably this increase it due to the drugs!
Not to put too finer point on it but the bike doesn't look like it would have been used to Ditchling hill repeats under heavy watts! GWS again..
