The Russian cycling federation has suspended three cyclists for using banned substances, local media reported on Monday.
Ilnur Zakarin, 19, who won the junior time-trial road race at the 2007 European championship, and 22-year-old Yekaterina Melnikova were both handed a two-year ban for using the performance-enhancing anabolic agent metandienon.
Meanwhile, mountainbike racer Kirill Bozhenko, 22, was banned for one year after he tested positive for banned stimulant carphedon.
