The aerodynamic benefits of the Chris Froome descending style may be up for debate, but most people would agree it’s not the safest way to cycle down a hill. This video recently posted to Facebook appears to back that up.

A Colombian cyclist’s headcam captures footage of another cyclist passing him. We see that person drop down off the saddle and onto the top tube a la Froome, but then it all goes awry in spectacular fashion.

It could have been worse though. A large truck comes to a sudden halt in the adjacent lane having avoided hitting the faller.

The question is, what caused this unconventional dismount? The footage is a bit grainy, but the road itself seems clear. The cyclist instead appears to fall the moment they try and start pedalling.
