I have a 1989 Expert and a 1987 Expert in the same size frames, and i measured them rather crudely one day and they are different geometries. IIRC, The 1989 had a less relaxed head tube angle as the 1987 had. i recall it was a couple degrees steeper. When i find the sheet that i noted these items i will post them here so others can get the idea.
