A former teammate of Lance Armstrong who testified against the seven-time Tour de France winner in a doping investigation has spoken about the massive scale of cheating in cycling.

Tyler Hamilton told Al Jazeera’s Paul Rhys that he, Armstrong, and their U.S. Postal teammates robbed “clean” riders out of victories, but that they were among a majority of cheats.

Hamilton, who helped Armstrong to Tour de France wins in 1999, 2000 and 2001, is serving an eight-year ban for doping. At 41, his career is effectively over.

A 20-page affidavit of his testimony was released as part of the U.S. Anti-Doping Agency’s findings. Hamilton has also written a book covering his allegations against Armstrong, cycling teams, and the International Cycling Union.
