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.
That would be interesting. I used to have a case hardened shotgun. It was almost tiger striped. I think it was an H & R, don't remember what I did with it.
Even though I generally prefer color on bikes, I think the white looks good. Pics are my 1991 Serotta NHX in fluorescent pink and orange, and my 1990 Colorado II in pink and onyx. I have two pink Cannondales as well.
I think it's unlikely that they made an 11 speed compatible freehub body for that hub but you might check with DT. I'm guessing that you would need a new rear wheel to change to 11 speed. The 11 speed freehub body spline length is a couple of mms longer on 11 speed hubs. The only workaround...
That should work. Believe it was only made with a 35 mm clamp but new ones came with shims. Be sure to get a dual pull version. There's also a top pull version.
Guessing that eliminating as much housing as possible is partially a weight weenie thing, but it does reduce cable friction - especially helpful on the rear derailleur.
Try looking for the serial number on the underside of the seat stay, usually non drive side. It's approximately 1989 but I think the LX rear derailleur is later.
Have you seen a 31.8 stem for a 1-1/4 steerer? You might need to get a quill adapter. Then you can use whatever stem you want.

CAAD5 was introduced for the 2000 model year and ran through 2003. I don't see that paint in any of the catalogs but it's fairly common for different paint schemes to show up. I don't think the geometry changed but a large in 2000 became a medium in 2002. Here's the chart from 2000.
