if you call cannondale, i think the number is 1800bikeusa, with the serial number, they can tell you the exact size and specs, and year it was made. i think all cannondale roadies went to STI's in 1992. $200 is fair id say. on teh high end of fair. $150 would be a more fair deal for the buyer though. check the frame for hairline cracks at the welds on teh rear dropouts, they aren't the kind prone to it, but always check. i always loved that airbrush zigzag they did for 2 years
