Well my bike isn't a Concorde persay. I just have a Concorde Prelude frame from say, 10 years ago. Its steel, Columbus SL of course. I love the feel of the frame. I payed like $200 CDN new for it. One store in Toronto is still selling it for like $400 CDN new. I put Shimano 600 components with a Deore XT headset (I cut the fork about 1.5mm to small so the 600 headset wouldn't stay tight due to the tall stack height), Cinelli stem and handlebar, Eggbeater petals, Ambrosio Elite rims with 600 hubs and DT spokes, and easton tape. The fell of the overal bike is great. Its fast too for a 22-23 lb bike. I have gotten to play with a few of the new Concorde bikes. I like the feel of them. They continue, after 10 years, to have the same consistency in ride quality. You will enjoy it.

Have Fun and Keep Riding,

Brian
