You can't compete in the u23 WC if you have a contract with a Pro Tour/World Tour team. That's why Gallopin could ride the u23 WC last year after doing the Vuelta, but Van Garderen couldn't (even if he had had any interest in doing so, which is doubtful).Bye Bye Bicycle said:TvG was already pro but still age wise U23 when riding last year's elite TT worlds (ending 24th). Same for Dominique Cornu in 2007.
