Which French company introduced the first system using a cable and pulley arrangement in 1938?
Answer
Simplex.
Following the initial conceptualization and manual operation of derailleurs, the next critical evolution involved improving actuation mechanics. In 1938, the French company Simplex made a significant engineering departure by introducing the first system that utilized a cable and pulley arrangement instead of direct mechanical linkage or rods. This innovation allowed for the management of chain tension and movement between sprockets using flexible cables, making the shifting process vastly more practical for use while riding dynamically.
