Wiggins said he was focusing on Evans.
"It's never over until it's over, and obviously Cadel is still the defending champion. You saw today, he just never gives up — and that's going to be the Cadel that we are going to see," Wiggins said. "It's one day down of many to come, so just savor today."
Asked if it was a two-man race, Wiggins said: "It's looking that way."
Team manager Dave Brailsford acknowledged Sky would be having an upbeat evening Saturday for the stage win and yellow jersey, plus other positive signs like strong climbs from Richie Porte and Froome.
"We managed to stay out of trouble during that first week, that was important. We had a bit of a question mark about Richie because he crashed three times yesterday," he said. "But he was good."
"And Froome showed (them) today ... Everybody was, 'You know in the Vuelta, where does this guy come from?' He showed today he can back it up. And he's one of the best climbers in the peloton right now."
The stage marked the first of three summit finishes this year. Nimbler climbers took the limelight after a first week dominated by sprinters across the flatter regions of Belgium and northern France.
The final ascent to La Planche des Belles Filles, at 3.1 miles, was relatively short as far as the Tour's biggest climbs go. But it was steep, with a grueling 14-percent gradient in the last 500 yards.
The Tour, in its 99th edition, had never previously led riders to La Planche des Belles Filles. According to the legend, centuries ago, a group of beautiful young French women — the "belles filles" — committed mass suicide in black waters of a lake to escape the looming clutches of Swedish invaders. But the leader of the Nordic horde had fallen in love with one of the women, and pulled out her lifeless body — carving a wooden epitaph to honor them.
The three-week race takes riders on another bumpy ride on Sunday, with seven climbs in the 97.5-mile loop from Belfort to Porrentruy in Stage 8. The Tour ends July 22 in Paris.
