Close. Actually - I did have an American Classic (AC) 350 rim on the back and still have one on the front. I had to replace the rear rim (Mavic 33) since I broke a spoke on the AC 350 and it went all out of whack and could not be re-trued. However, the rear is a Zipp 215 hub; front is Zipp 100.
Can you enlighten me as to what you mean by the "freehub is dragging?" And what would I need to do to correct?
