The Italian was part of the break of the day, who were left to contest the stage victory by the peloton, led by Primož Roglič's Jumbo-Visma team.
Fausto Masnada (Androni Giocattoli-Sidermec) beat Conti to the line to take the stage win, after the pair had attacked the breakaway almost 30km from the line. Further Italian success came courtesy of Giovanni Carboni (Bardiani-CSF), who moves up to second overall and takes over the lead of the youth classification.
Former race leader Roglič, who now lies in 11th place, 5:24 behind Conti, hit the deck in a mass crash early in the stage. He continued with no problems though, aside from a cut to his hip.
