One of the true legendary names in the world of cycling. Few, if any, bicycle makers have had the impact on modern cycling as Cino Cinelli.
Cino was a successful racer in Italy and began building his innovative frames in Milan just after WW2, creating many new features which made his frames stiffer and more aggressive.
Fausto Coppi was one of the first to use these new features when he raced on a Cinelli frame in 1947. They were produced in small quantities until the company was sold to A.L. Columbo tubing group in the late 70's. Cinelli frames made up until that point where used for Olympic and World Championship teams and discerning riders.
Cinelli also was known for components, his steel stems and bars where classic. There where a number of innovations that he brought to cycling. The first clipless pedal, the M71 was released in 1971. The first aluminum handlebars to be accepted by the pros. The first plastic saddle, the Unicantor was designed in 1962 and became the model which all of today’s saddles are based.
