Team Katusha's Ilnur Zakarin secured a memorable first victory on stage 17 of the Tour de France, but it was not a good day for overall title contender Nairo Quintana.
Quintana, one of the pre-race favourites and considered one of defending champion Chris Froome's main challengers, was dropped on the hors categorie climb at the end of the day's 184km route from Berne to Finhaut-Emosson.
It was another flawless performance for race leader Froome in the mountains, as he followed up Richie Porte's attack in the closing kilometers.
Only Froome was able to stay with Porte as they shed the bunch. Quintana tried to follow but couldn't maintain the pace.
“Brings back memories,” Froome said of riding with his former Team Sky partner. “I’ve said it before; I really think Richie is one of the best if not the best climber in the world. He proved today why he’s fighting for a podium.”
The late burst allowed Froome to extend his overall advantage to 2:27 over Bauke Mollema and 2:53 over Adam Yates.
Quintana, meanwhile, now finds himself 3:27 back in fourth, with Porte up to sixth.
Russian Zakarin claimed victory on the day after breaking away from Jarlinson Pantano and Rafal Majka on the final climb, having caught to to the two frontrunners with about 8.5km to go.
