It's funny that in some thread there was Merckx - Pogacar comparison.. So wool shorts, natural chamois, steel frame, aluminum rims w 32 spokes, 7 or 8 speed cassette w downtube ,friction shifters, diet regiment that included mandatory massive meat consumption.. Months off in off season, folklore about lifting weights, doing any cross training, walking, ..glued on tires that often failed for a variety of reasons!! Asking a Eddy era racer if they were aerodynamic.. Their bikes and wheels were cutting drag or reducing watts..would have looked at you as crazy.. Tell old racer that they need a wind tunnel.. Would have laughed you out of the room.
