Description:
A classic French clamp-on front derailleur produced by Simplex, designed to deliver fast, reliable double-chainring shifts. Engineered with Simplex’s period-defining combination of a rigid chrome-plated steel guide cage and a lightweight mounting body, it clamps firmly around standard 28.6 mm steel seat tubes. A fundamental, catalog-correct component for outfitting vintage French steel racing bicycles from Peugeot, Mercier, or Gitane with authentic period drivetrains.
