How do you tell the difference between a 1989 Cannondale ST 400, ST 600 and ST 1000?
I just bought a 1989 Cannondale frame I'd like to build up to a single speed. For 45 bucks I couldn't pass it up. I downloaded a 1989 catalog and found it looks like a ST400 but there are two other models that year in the Sport Tourers. How do I tell the difference in the three models without the componets? Or am I an idiot thinking the frame would be different and not just the componets? Thanks for your replies. Johnny.
