Eugène Christophe, the French cyclist born in Paris on January 22, 1885, is considered the inventor of the pedal hook. In 1925 he sold his invention to Poutrait-Morin(now known as Zéfal). He was director of this company until his death in 1970. Since then, Zéfal has been selling these legendary Christophe pedal hooks. Sold in pairs.
