Cino Cinelli's brother Giotto had been making steel stems since the late 1930s in Florence, Italy. They moved the business to Milan after the Second World War. In 1963 Cinelli began commercially producing alloy stems and matching handlebars and it wasn't long before Cinelli bar and stems became the choice of serious athletes and connoisseurs.

The 1A ("A" stood for aluminum) stem and Cinelli bars were first shown at a trade show at the 1960 Rome Olympics. We believe consumer production of these new aluminum stems and bars didn't begin until 1963.

Those first components had a polished, non-anodized finish. The classic clear anodization that gives Cinelli stems and bars that luxurious "milky" finish began in 1965.

Of the two classic Cinelli bars, the Model 66 Campione del Mondo and Model 64 Giro d'Italia, the 66 has the deeper drop, about 160mm center to center.

Weight of a 42cm width is about 333 grams.
