Cycling in 2010 was struck by a series of crises that threatened to (wipe) out most of its efforts to fight doping, with the sport's two (biggest) names involved in scandals.
Seven-times Tour de France champion Lance Armstrong was embroiled in a U.S. federal investigation triggered by (former) team mate and disgraced 2006 champion Floyd Landis's allegations, while three-times winner Alberto Contador (failed) a test for the banned anabolic agent Clenbuterol.
