Info about my vintage Cannondale

[writerbiker]

Hello, new here. I just scored a 1984 Cannondale at a Goodwill in Maryland. Can someone tell me how I can tell exactly what model it is. From looking at the catalog, it could be an ST300, ST400, or ST500. I don't think the bike has a drive train that would have been specced from the factory, so I am having trouble matching to the catalog descriptions. It has a Sugino 48/40/28 oval crankset and a Deore rear derailleur. The brakes, downtube shifters, and front derailleur are Shimano 600.

Congrats!! OK, let's start with pics showing paint color, and closeups of the components; derailleurs, brakes, crank, etc. Plus a few of the entire bike, drivetrain side please. The serial number will tell us size and build date; there should be a number stamped under the chainstay or seatstay, dot-matrix style.

It's going to be able to differentiate between the two 1984 ST models as the catalog we have only has specs for one. I'd guess the specs are for the ST-500 but even that isn't clear. Since the frames were the same, the model is essentially determined by the components that are on it.
