London -Tour de France stage winner Edvald Boasson Hagen has signed a new three-year contract with Team Sky, the British squad announced on Wednesday.
The 24-year-old Norwegian secured the UK team's first triumphs at road cycling's premier event when he won two Tour de France stages in July.
Boasson Hagen, who had one year left to run on his existing contract, has now signed up with Team Sky until the end of the 2014 season.
"I have enjoyed two great years at Team Sky and really enjoy being part of this team," Boasson Hagen told the squad's official website.
"I have some great team-mates here and the support staff are also fantastic.
"They have helped me improve a lot over the past two seasons and I hope they can help me get even better in the future."
Team Sky principal Dave Brailsford added: "Edvald is widely recognised as one of the most exciting talents in the pro peloton and we are delighted that he has chosen to stay with Team Sky for another three seasons.
"No-one quite knows yet where his true limits lie and we will continue to work tirelessly to support him to fulfil his potential."
