In a descent, around ten riders went to the ground, including Girmay but also Ben O'Connor and Einer Rubio. Restarting a few moments later, the Eritrean slipped again in a wet corner. It was too much for him who decided to put his foot down.
This is already the sixth retirement in this Tour of Italy.
Two years ago, for his first participation in the Giro, Biniam Girmay won the 10th stage. But on the podium, he was very unhappy, receiving the Prosecco cork in the eye, forcing him to give up again.
