I've always been curious about mine but there is frustratingly little information out there about the geometry.
I did! 74° HT and 74° ST with a 57.5cm TT (measured CTC). 25" / 63.5cm frame size. 70mm BB drop, measured. Calculated fork rake of 49mm with a calculated trail of 46mm (give or take a mm or two). Apart from the Paramount, it took Schwinn a while--into the '80s--to release really any geometry information on lesser bikes. Often, it was just a 58cm frame that they would give seat tube angle, head tube angle, and wheelbase information on. Well, that and frame size which was always a CTT measurement.
