"The 1980 cutoff used by l'Erioca is even more strict (if enforced), because it would automatically eliminate some of the above. However, there were many bikes sold in 1983 an even later that would still conform within the physical criteria."
Raced as well as sold. A cursory look at photos of the 1984 TdF shows half the machines raced had toeclips, non aero brakes etc. Even a year later Hinault's machine had non aero brakes. I spent the day on my '85 Peugeot PX totally original and totally and wholly CR List worthy. But hey it ain't my list or my rules. I think 1983 is off by two solid years. 1980 is just dumb.
