- French cyclist born on the 22nd of January 1885 in Paris, Eugene Christophe is viewed as the inventor of the toe-clip. In 1925, he sold his invention to Poutrait-Morin (now known as Zefal), and was the Director of the company until his death in 1970. Since then, Zefal never stopped selling these legendary Christophe toe-clips. * Material : Chromed steel * Pronged toe-clip : Simple * 2 sizes : S/M and L/XL
