Though there are no Tour de France winners on the list, the U.S. Anti-Doping Agency has sanctioned five cyclists for doping in the past two months - an unusually high number for a single sport, and one that is expected to keep growing over the next several weeks.
The recent surge has resulted from a combination of factors, including information provided by Joe Papp, a former midlevel rider who has been a key USADA informant since admitting in 2006 he cheated.
The cases create another problem for a sport that has been in turmoil, with Lance Armstrong under federal investigation and this year's Tour de France winner, Alberto Contador, among the latest to be accused of doping.
Both USADA and USA Cycling are based in Colorado Springs.
