Some history of the Italian national championships here: http://www.cyclingnews.com/road.php?id=road/2003/jun03/italy03/default
"Girardengo is unquestionably the dominator with nine triumphs, followed by Learco Guerra with five and then the three great mythical figures of Giro de Italia; Coppi, Bartali and Binda, all of them with four triumphs."
