7. Lance Armstrong (1999-2005)
Armstrong competed in the Tour four times in the early-to-mid 1990s, completing it just once (1995 - 36th). After beating cancer, Armstrong started beating cyclists, too. He won seven straight Tours, two more total than anybody else, with his closest win coming in 2003 when he beat rival Jan Ullrich by 1 minute, 1 second. Armstrong dominated in the doping era. Of the eight other riders who joined him on Paris podium, seven have been linked to doping allegations. And, of course, so has Lance, who has steadfastly denied them and passed tests time and again.
