How to crash when your crank cracks...

Postby wombatK » Wed Apr 01, 2015 11:02 pm

Fly6's 2nd Best Video submission for March is pretty interesting. Rider does a good job of
tucking and rolling with the crash, and might have escaped without too much injury

Same for the following rider.

Well he did better than I did when that happened: I went straight over the bars and head first into the tarmac, demolishing a helmet in the process.

Don't think he tucked. He stood and went out of saddle just before the crank snapped.

He dropped on the top tube, lost balance. His hip took most of the force then the elbow.

That'd make you a bit cranky....
I had a thought, but it got run over as it crossed my mind.

After dropping onto the top tube from the standing out of the saddle position, any pain caused by hitting the ground would not have been noticed. :shock: and could explain the tucking up manoeuvre. :wink:

It would have ended much worse if he'd stuck his left arm out to break his fall ... that's how most
collarbones and wrist-breaks occur in crashes. Taking all of your body weight on an extended
arm will mostly buy trouble.

Instead, the rider kept it bent and and close by his side most of the way to the
ground (still gripping handlebar). His first contact with the ground was his foot, then knee,
and back side of his hip. His left forearm arm was not extended, and forarm/elbow hit the ground
almost simultaneously (stop frame it at 0:06 s) as he rolled onto his back. So his weight was taken
up progressively across his body ... not all on an extended forearm, and his left hand didn't
touch the ground.

It's also nice to see how quickly right shoe released from the pedals ... as his thigh hit
the bar within around 0.15s of the snap.

It was the upper part of his right thigh that hit the top tube .. so he should be ok for producing
any future heirs and successors.
