On May 4, 1940, Tullio Campagnolo patented his first version of the dual-rod gear changer, so-called because it used two rigid levers.
The rod gear evolved into the Corsa 1001 version with which Gino Bartali won the Tour de France in 1948, and then into the Paris-Roubaix 1002 version, so-called in honor of Fausto Coppi for his victory in the homonymous race in 1950.
But gear technology had arrived at a turning point: the first derailleur with an articulated parallelogram, the Gran Sport 1012, debuted in 1950.
