In a communiqué today, the International Cycling Union, which governs the sport, noted that only one Tour rider was found guilty in tests for EPO, or erythropoietin, the oxygen-bearing drug that has been a scourge for several years, and concluded that "the problem of EPO no longer influences high-level bicycle racing".
