Former team leader Michael Rasmussen was thrown out of the 2007 Tour de France when on the verge of winning the race and was subsequently banned for two years after lying about his whereabouts over missing doping tests that year.
As a result, Rabobank's withdrawal led to an angry rebuke from British rider David Millar, who Tweeted: "Dear Rabobank, you were part of the problem. How dare you walk away from your young clean guys who are part of the solution. Sickening."
Millar later added, "Just in case anybody needed reminding, Hein Verbruggen is Dutch. He's leaving a fine legacy," in reference to the former UCI president, who has been dragged into the doping controversy but denied any wrongdoing.
Armstrong, meanwhile, will make his first public appearance since the publication of the United States Anti-Doping report into systemic doping by the American at his former US Postal Service team.
The 41-year-old, who stepped down as chairman of the Livestrong charity he founded, will attend its 15th-anniversary gala evening in Austin, Texas, tonight.
Former Australian cycling Stephen Hodge is the latest casualty of former doping in the sport. The vice president of Cycling Australia has resigned from the post after admitting doping during his career, which ended in 1996.
Hodge said: "During a stage of my career as a professional cyclist, I took performance-enhancing drugs, a decision I am not proud of. I am sorry I did it. It was wrong."
