My oldest bike is a 1983 Bianchi Italian race bike. It has "stage race geometry," which means slightly lengthened chain stays and more fork rake for all day cruising and a touch more stability than a full on, nervous, twitchy racer, but it's still plenty fast and lively. The chrome's in great shape, too!

I also have a 1993 Bridgestone XO-1 which has become a bit of a cult/collectable bike. That particular model year had a couple of unique features and '93 was near the end of Bridgestone's presence in the U.S. market...plus, it's orange!
