Maybe every race! but carbon fails catastrophically where even the cracked and bent frame posted by Cuda above was still rideable - would not have dumped it's rider on the pavement.

I'm reminded of the failure of Artemis Racing's America's cup yacht - it literally exploded. Boats and bikes have high concentrations of stress - unlike an aircraft stabilizer for example - and there are some limits in the finite element models that validate the designs.

Was the corpse of the rider that bike took out in the big red & white bag?

It all makes sense.

I think it's called "the racer's edge"?
Brilliant! What an ingenious use for those old dead Lithium-Ion fire hazard batteries, bicycle ballast!
