Thanks, Marty. That will be the ultimate step to take. In this day of finding just about everything on the 'net, I was hoping that someone would know of a resource that has the info, or a method to figure it out. Perhaps not!

I have no idea if the components on the bike were the originals, as I bought the bike used from a racer/bike shop mechanic back in the early 90's. When I bought it, the bike had kind of an odd mix, Shimano 600 Ultegra drive train and brakes with Campy seatpost, bottom bracket, Cinelli stem and handlebars, Mavic wheels, etc.

I guess if nothing else works, I can just pop in with the serial number next time I'm over there.

But maybe someone out there knows a faster, easier way.
