Paul de Vivie was publisher of Le Cycliste, an early
champion of derailleur gears, and father of French bicycle touring and
randonneuring.
De Vivie imported machines from England. In 1889 he made
a bike of his own, called La Gauloise. It had a diamond frame, chain and a
single gear. De Vivie was riding the col de la République (10 km south east of
St Etienne) in 1889 when one of his readers overtook him - smoking a pipe. De
Vivie felt challenged but also trapped: if he lowered his gear, he would go
slower on the flat. But on the gearing that he had, he could not climb hills
fast enough either. British thinking favoured epicyclic and planetary gears,
concealed in the rear hub. De Vivie created the derailleur. His first had two
chain wheels; the chain had to be lifted by hand from one to the other. He then
placed two chain wheels on the left side. The combination gave him four
gears.In 1901 Velocio combined his invention with the four-speed proteon gear
of the English Whippet, which used a split chain wheel. Pedalling backwards
made the two halves of the chain wheel open. Pawls then secured them in one of
four positions. De Vivie's development appeared in his Cheminot in 1906, the
first derailleur. He overlooked taking out a patent and made barely any money
from an invention which changed cycling.
It has been said that de Vivie invented something which
already existed, in Britain, and simply made the derailleur better known.
Traditional cyclists did not appreciate his gears. The
organiser of the Tour de France, Henri Desgrange, dismissed them in L'Auto as
fit only for invalids and women. De Vivie campaigned for his invention and rode
every morning up the col de la République for the joy of passing riders without
them.
