 Things changed when Ivan Basso 's team came forward on the third climb of the day to set a much faster pace in the peloton , and Basso himself attacked and came free , with only Stefano Garzelli holding his wheel . They caught some members of the morning breakaway , as that group also splintered , but were eventually themselves caught . Danilo Di Luca launched an attack on the fourth climb of the day , and for a time he and Menchov were clear of the other GC contenders , but they were also caught — the top seven in the GC were unchanged after this stage .
