Kazakhstan's Alexandre Vinokourov sprinted to victory in the men's cycling road race on Saturday, crushing British hopes of gold on the first full day of competition at the London Olympic Games.
Dutchman Bauke Mollema, the strongest and smartest of the breakaway riders, who had three top 10 finishes on the Tour, won the 189.5-km stage from Laissac-Severac L'Eglise but the action was elsewhere.
Lopez prevailed at the end of the 170-km trek from Grenoble, 15 seconds ahead of Roglic, who extended his advantage over fellow Slovenian Tadej Pogacar to 57 seconds, four days before the final parade in Paris.
Roglic leads Pogacar by 40 seconds and Colombian Rigoberto Uran by 1:34 as the race is turning into an all-Slovenian affair following Bernal's disappearance.
The defending champion came seventh, one second behind stage winner Michael Matthews of Australia as Aru, who started the day with the yellow jersey on his shoulders, lost 25 seconds to the Briton in the final effort, a 600-metre climb at an average gradient of 9.6 per cent.
Portugal's Rui Costa kept his composure in a tense finale to upset the favourites and clinch the cycling world championships road race on Sunday.
Frenchman Romain Bardet timed his final effort perfectly to win the 12th stage of the Tour de France on Thursday, setting up a thrilling second half of the three-week race as defending champion Chris Froome showed a rare sign of weakness.
