Although vintage, I don't think it has much value. Parts will be tough to find. I have a Cannondale of that era. It started life as a ST700 which I did a frame swap out for a ST1000 frame. If you go online, you can see older Cannondale catalogs. I commend Cannondale for always offering a true touring bike. Their top of the line touring bikes had cantilever brakes, where as the ST 600-800 had side pull. The front crank had a 28-44-50 elliptical bio pace design. The rear had a 6 speed freewheel. The gear levers were mounted on the down tube. The frame geometry was also different. If the rear wheel is very close to the seat tube, it wasn't a touring frame. What color is it? Yellow? Each year they changed their color. To spruce mine up, I had a Brooks Saddle on it, matching handlebar tape, and fenders. I also had the original Cannondale front and rear racks and I converted the gear shifters to STI's. Being Aluminum, it was relatively light weight. I put thousands of miles on it. I now ride a Comotion. If you give me your email, I will send you a picture.
