Lemond Bikes dissolved in 2008 as a result of a conflict between Greg LeMond and Lance Armstrong .
LeMond is a vocal opponent of performance-enhancing drug use , and at times his commercial ventures have suffered for his anti-doping stance—as in 2001 , when he first accused Lance Armstrong of doping and sparked a conflict that led eventually to the dissolution of his partnership with Armstrong 's primary sponsor , Trek Bicycles in 2008 .
