Wiggins 'never imagined' being Tour de France favourite
"I'm really proud to be part of such a strong unit going into the Tour de France," he said.
"The team's preparation has been perfectly managed and our form this season gives us a great chance of being successful.
"I've been waiting for this moment for a long time and I'll do everything I can to win the Tour de France."
Cavendish, a winner of 20 stages over the last four Tours, says he is prepared to sacrifice his own prospects of success for the goal of Wiggins winning the yellow jersey.
"I know the push for the General Classification podium will make it more difficult for me to repeat the success I've enjoyed the last few years.
"But I'll compete and - as always - I'll dedicate myself to making it a successful Tour for Team Sky and, let's hope, for Britain."
Team Sky's third British rider is Chris Froome, who will compete in his second Tour de France. A strong climber, the 27-year-old was second in the 2011 Vuelta a Espana, and he recently helped Wiggins in his Tour de Romanie and Criterium du Dauphine successes.
Team Sky squad for Tour de France:
Bradley Wiggins, Mark Cavendish, Edvald Boasson Hagen, Bernhard Eisel, Chris Froome, Christian Knees, Richie Porte, Michael Rogers and Kanstantsin Siutsou.
