I guess that from about 1952 on nearly every pro would have chosen a Campag Gran Sport
Strangely not.
I don't think you read my post quite carefully enough. My point was that the pros would have chosen Campag if they could have done, but they were committed by their contracts to use whatever rubbish their sponsor chose. Nationalism was a strong factor, so if you were French you would have a huge struggle to use non French kit. If you look at that list you will see how effective this was before the Japanese kit arrived.
One notable exception was Coppi, who caused a big stir in 1949 by insisting on using Simplex for the 1949 TdF, which he won. Tullio was very annoyed with him because he thought Coppi should use his Cambio Corsa which Bartali had won with the previous year - of course, Coppi did not have the same power of prayer behind him that Bartali had enjoyed!
Ah. You’re right I didn’t get your meaning.
And yes, I noticed the nationalism in the list of equipment, Anquetil still riding (and winning) on simplex push rod in 1961! I’m sure the pills helped.
