Filippo Ganna is one of the most powerful riders in the WorldTour peloton, and managed to produce the watts to defy gravity on the final climb of stage 5 of Tirreno-Adriatico but then his chain failed a similar test as he raced to the finish in Pergola.
The Ineos Grenadiers rider was about to try to sprint to the line or chase down Fredrik Dversnes (Uno-X Mobility) who was still clear after being in the break of the day. Suddenly he was left spinning his legs as his rivals rode away from him.
