I have an opportunity to purchase a 1990 Daccordi 50th Anniversary road bike. It is in very good shape, but may need a new cassette. It has Dura-Ace components. It fits well. Anyone know about this bike and is it a good buy at US$400? Was supposedly US$3000 when new in 1990. I know alot has changed technologically in 14 years. Any thoughts would be appreciated.
