Two-time Tour de France winner Chris Froome is to extend his contract with Team Sky until the end of 2018.
Froome, who won last year's Tour to go with his 2013 crown, announced the news during the team's training camp in Mallorca.
"Team Sky have been fundamental to my success to date, so it was a very easy decision to commit to the team until the end of 2018," Froome said in a statement.
"Their values are my values and I am proud to ride for a team that has shown you can win the biggest bike races in the world clean.
"2015 was a fantastic year for me both professionally and personally and this is a great kick-start to 2016. I am more motivated than I have ever been and I have got big targets for this Olympic year. I can't wait to start racing."
Froome has been with Sky since the team was founded in 2010.
The Kenyan-born rider, 30, is hoping to make 2016 his most successful season yet as he targets a Tour-Olympic double.
Team Sky principal Sir Dave Brailsford said: "Chris is not only one of the most talented and dedicated riders in the world, he is also a fantastic ambassador for the sport. Team Sky is proud to have him as our team leader.
"He is a winner and it is a great boost at the start of the new season that he has committed to stay with the team until the end of 2018. He is hungry for more success and we will help him achieve it."
Froome plans to start his 2016 campaign at the Herald Sun Tour in Australia at the start of next month.
