Not sure on frame weight, but I have a 58cm Reynolds 531 steelie (Trek badged) with Campy Record, Mavic wheels (sew-ups) Cinelli bar and stem, Selle San Marco saddle and Dura Ace pedals that weighs in at 21.5 lbs. I built her in 78-79 (except for the pedals which came later).

She seems down right heavy compaired to my Madone. LOL.
