Video: On-board stage 5 Tour de France crash footage is absolutely nuts

The sheer number of riders that went down in this spill and the ease at which they all fell in the wet has to be seen to be believed.

The relationships between the Tour de France and Velon on the production of more on-board GoPro footage than ever really is producing some great stuff.

The clip from stage 5, below, really hammers home just how dangerous the pro bunch is at high speed when it's wet, despite the incredible bike handling skills of most of the riders.
