The incident took place on the run-in to the climb as the GC teams fought for position, with Movistar’s Rory Sutherland moving left on to the wheel of a Trek-Segafredo rider.
Unfortunately this meant that he cut across Eugenio Alafaci, who responded angrily, picking his bidon out of his bottle cage and flinging it with all his might onto Sutherland’s back wheel.
Instead the Australian simply turns around and drops back, appearing to just put his arm on the back of the Italian rider, and exchanging a few words before getting on with the job in hand.
