US Even the 83 catalog does not list weights My 83 Comp weighs 24lbs 23 inch frame and my 83 SC 23 inch frame weighs 25lbs. Actual weight visa a hanging scale. FYI out of the 8 bikes I have including 3 SC 74 79 and 83 the 83SC is just smooth and right. They all have they same tires same heights of bars and seats.
