The Union Cycliste International (UCI) has requested that anti-doping cases be opened against five riders after studying the data from their biological passports.

The best known of the five riders is former world champion Igor Astarloa (Amica Chips), who won the rainbow jersey in 2003 but was fired by the Milram team last year after registering irregular blood values. The others are 33-year-old Italian Pietro Caucchioli, who joined Lampre from Crédit Agricole in the winter, Fuji-Servetto’s Spanish rider Riccardo Serrano, Italian Francesco De Bonis, who rode for Gerolsteiner last year before joining Serramenti PVC Diquigiovanni, and Ruben Lobato Elvira, who is currently without a team having failed to find a contract after the Scott-American Beef (formerly Saunier Duval) team folded.
