Cinelli was founded in Milan in 1948 by Cino Cinelli, a professional road racer from 1937 to 1944, although the company timeline traces Cinelli stems and bars back to 1938–39. Its frames are famous, but the parts most buyers meet are cockpit components: the forged aluminum 1A quill stem (production from 1963), the 1R Record stem with its hidden binder bolt (1973), and aluminum drop bars including the model 64 Giro d'Italia and the deeper model 66 Campione del Mondo. Cinelli also sold the Unicanitor saddle, an early plastic-based racing saddle credited to Tommaso Nieddu of Turin and later co-branded with Cinelli. In 1978 the company was sold to Antonio Colombo, owner of Columbus tubing, and the Flying C logo designed by Italo Lupi replaced the older marks, a useful dating clue on stems and bars. For decades Cinelli bars and stems used their own 26.4 mm clamp size; Sheldon Brown dates Cinelli's change to the Italian 26.0 mm standard to 1998, and Velobase records some 26.0 mm Cinelli stems and bars from the 1990s, so measure before mixing parts.
