Cinelli moved to alloy production in 1963, later than other manufacturers because he was concerned about strength. Annual production of alloy stems and bars rose from 5,000 in the 1950s, to 7,500 in the early 1960s. By 1978 the figure was 150,000. He made no more than 700 frames a year. In 1974, he designed an aerodynamic bike on which Ole Ritter broke his own hour record. The staple product was the Speciale Corsa road model made from 1947. The Speciale Corsa also became known as the "Super Corsa" after a supplier sent decals that erroneously said "Super Corsa" instead of "Speciale Corsa."
