So, I have an opportunity to but a really cool bike, a 2001 CSI with F3 fork and Chorus 10 (pre-composite) group, Electron wheels. The bike has been sitting in a shop since 2001, used as a demo bike. I took the bike for a pretty thorough test ride and was very impressed with the way it rides, and extremmely impressed with the shifting and braking performance of the Chorus 10, WAY better than Shimano! I can get the bike for a really good price. What do you think, should I buy it?
