Bradley Wiggins has signed a four-year contract with Team Sky.
The 29-year-old British rider said: "It's been an amazing year for me and my ride at the Tour de France [where he was fourth overall] has given me the drive to aim even higher.
"I know I can continue to develop and Team Sky is the perfect place to make that happen. Moving to Team Sky is like coming home."
Dave Brailsford, the team principal, said: "Brad will be at home for Team Sky. It's the perfect fit and he will be a marquee rider for us.
"Brad was a real revelation at this year's Tour de France and has been hugely successful for British Cycling and his Olympic success has brought wide recognition.
"His presence will not only help us on the road but with the wider aims of inspiring people to not only follow the team but also to get out and ride, whatever their age and ability."
Wiggins joins Team Sky from the American Garmin-Slipstream team. His previous teams are Linda McCartney (2001), Française des Jeux (2002-2003), Crédit Agricole (2004-2005), Cofidis (2006-2007), High Road/Team Columbia (2008) and Garmin-Slipstream (2009). He has signed to ride for Team Sky until the end of the 2013 season, by which time he will be 33.
