Campagnolo was founded in Vicenza in 1933 by Commendatore Tullio Campagnolo. The company soon expanded, focusing on the three fundamental concepts that would also characterise its future – performance, technological innovation, and quality of products and services. 75 Years have passed and Campagnolo continues to create products for the extremely high standards of professionals, raising the quality, technology and design levels every year. The additional speed led Campagnolo to devising a new support structure for the last six sprockets in two subsets. The form of the teeth on the Campagnolo Chorus 11spd Cassette is new and they have been treated to increase duration over time.
