The stunt performed by an unknown cyclist seems to have been well thought out. There is a ramp clearly visible on the edge of the hill and the landing ground must have been cleared of rubble as well. The rider followed suit of a French freerider Romain Marander who jumped over a group including Chris Froome in 2013.
Only two questions now remain. Was it Peter Sagan? And how much now do his buddies owe him?
