This photo features Georges Davoine, who came second in the 1922 Championnat de la Bicyclette Polymultipliée.
He was riding a Desvages bicycle fitted with a Le Chemineau derailleur.
Georges Davoine appears to have ridden the 1922 Tour de France and the 1924 Paris-Roubaix. I hope he wore a lighter jacket! The bearded bloke standing next to Georges in this photo, wearing the flat cap and official armband, appears in a number of photos of the period - he's clearly important, but I do not know his name.
