Famed component maker Cino Cinelli's brother Giotto had been making steel stems in Florence, Italy in the 1930s. The brothers moved the business to Milan after the Second World War.

Cino Cinelli began making alloy stems in 1963 (the 1A model) and it wasn't long before the Cinelli stem was the choice of serious athletes and connoisseurs. Different models came out over the years, including the Oyster featured on this page.

The Oyster was produced in the 1990s
