I also think Démare, because the Frenchiest French are from Île-de-France, but FDJ have no! rider from Paris, if I see that correctly. Beauvais is not that far away, though, the other riders have been born further away.
There's also the flag thing.
One aspect counting against Démare is that he doesn't look French at all to me. Who would you pick to play a typical Frenchmen in a film you're directing? I would go with Brunel or Pinot.
Pinot is also a known French denomination, so it must be:
1. Démare. 2. Pinot. 3. Brunel.
