Monsieur and Madame Diesnis (again, no forenames are recorded for them) are seen leaving their rivals for dead at the 1924 Championnat de la Bicyclette Polymultipliée. They seem to have won 100 Francs for being the second tandem to finish, with a further prize of 50 Francs for using a particular brand of wooden rims.

They are riding a Desvages tandem fitted with a Le Chemineau 3 speed derailleur and double chainwheel.

I rather like the aesthetic drama added by cracks in the glass slide.
