The Italian Olympic Committee performed surprise doping tests on new Tour de France leader Frank Schleck and his CSC team after Sunday’s stage, which concluded in Italy.As many as six riders were tested at CSC’s hotel, CONI confirmed Monday without providing further details. Fifteen more surprise tests were carried out by CONI on unnamed teams Monday morning. Labs usually require several days to analyse doping tests and no results were announced. The Tour crossed into Italy on Sunday with a stage that ended with a climb to Prato Nevoso, during which Schleck took the overall lead from Cadel Evans. The teams remained in Italy for a rest day Monday before Tuesday’s leg was to bring the race back into France.
