Discovery Channel Pro Cycling Team (UCI Team Code: DSC) was a United States-based professional road bicycle racing team. It was the continuation of the 2004 U.S. Postal Service Pro Cycling Team. Lance Armstrong, seven-time Tour de France winner, was its leader (albeit only during the Tour) until July 2005. From 2005 until 2007, the team was one of the 20 teams that competed in the new UCI ProTour.
