The Volpe is a very desirable bike. Yours is not even very old--- if its been stored inside you may not have much work to do. The Suntour components are very durable--I have them on several bikes older that yours and none of these compenets have worn out. If your derailleurs need adjustment, Yellow Jersey bike shop in Madison has the original manual posted on their website. ( http://www.yellowjersey.org/sturtech.html )
Enjoy your bike!
