WATCH: Tour de France rider’s $12k bike SPLITS IN HALF during crash
Moscon was involved in a smash with Canada's Michael Woods from the EF Education First team around 15km (9 miles) from the finish line on the 230km route from Macon to Saint-Etienne.
The hit, which happened on a tight turn, also took out Moscon’s teammate and defending champion Geraint Thomas.
Footage shared by Ineos showed Moscon standing next to his Pinarello Dogma F12 bike, which has been snapped apart.
He hopped on a replacement as the team battled back to join the peloton, but Thomas ended up losing time overall to rivals Julian Alaphilippe and Thibaut Pinot of France.
The stage was won by Belgium's Thomas de Gendt after a long breakaway, while Alaphilippe reclaimed the yellow jersey with a late surge.Also on rt.com Pedal pain: Cyclist displays shocking effects on legs during grueling Giro d’Italia (PHOTOS)
