Charles;
Search for the Trento Bike Pages on the Internet, go to the section on Italy and you might find something, a link or perhaps a contact who could point you in the right direction. You'll be smack dab in the middle of some nice riding, not to mention everything else Italy has to offer.
There is a person on the Touring list who might be able to help you, Valter Fumero. He's in Western Italy near Torino but has extensive knowledge of cycling in Italy.
