Material: Chromed steel
The name Cambio Vittoria evokes thoughts of the famous Vittoria Margherita shifting, popular on racing bicycles during the 1930s to early 1940s. These steel clips were made by that same Italian company.
We added old photos to this set which illustrates their use. During one mountain stage of the 1949 Tour de France we see Fauto Coppi crearly has a long frame pump mounted on his bike.
