Gene, it's an ST series (sport/touring) frame. More relaxed geometry than an SR (sport/racing) frame.
Perfect for Gentlemen Of A Certain Age. If you catch my drift. And the 700c's exagerate the clearance somewhat. Strangely enough, with 27's it gets a little tight with a robust 27 X 1 1/14 like a Michelin Continental.
PastorBob, those are actually '85-86 decals on an '87 frame. Cannondales of that era used only top tube and chainstay decals with a teeny one at the top of the seat tube- downtube decals came later on.
