Lance Armstrong -- 11 Cycling Teammates RATTED Me Out

11 former members of Lance Armstrong's United States Postal Service cycling team TURNED on the disgraced athlete -- and testified against him in an investigation by the U.S. Anti-Doping Agency.

The USADA announced .... the cyclists who provided evidence to the organization include George Hincapie, Tyler Hamilton and disgraced former Tour de France champ Floyd Landis.

“The U.S.P.S. Team doping conspiracy was professionally designed to groom and pressure athletes to use dangerous drugs, to evade detection, to ensure its secrecy and ultimately gain an unfair competitive advantage through superior doping practices,” the USADA said in a statement.

“A program organized by individuals who thought they were above the rules and who still play a major and active role in sport today.”

The USADA says its investigation into Armstrong uncovered "the most sophisticated, professionalized and successful doping program that sport has ever seen."
