There was another dominant performance from the 28-year-old as he conquered the gruelling Mont Ventoux -- at 150 miles the longest stage of the Tour -- just days later.
Froome had to be given oxygen after his arduous efforts but his obvious fatigue did not stop questions being asked.
In an attempt to end the finger-pointing surrounding Froome, Team Sky gave French newspaper L'Equipe data of 18 of his climbs since he made his major breakthrough in 2011.
The French newspaper's sports science expert, Fred Grappe, was satisfied the results were consistent with doping-free riding.
Commenting on the spectre of doping on broadcaster Eurosport 2 Froome said: "On the back of the history of the sport and recent revelations whoever was wearing the yellow jersey was going to come under a lot of scrutiny.
"I hope I've shown the sport has changed and we as the peloton won't stand for it any longer."
Wiggins, who pulled out of this year's Tour because of a knee condition, told CNN that cycling's troubled history is now most useful when it is used in a light and shade comparison to where the sport was -- and where it is heading.
"It's had a tainted history but I think all that is a reminder of where the sport was and where it is now," he said. "And it's in a great position."
And after emerging from shadows of his own, Froome will agree the future is bright.
