A dated timeline of Campagnolo from Tullio Campagnolo's birth in Vicenza in 1901 to the minority investment of 2026: his first patent of May 1933, the cam quick release of 1943, the Cambio Corsa and the Paris-Roubaix, the Gran Sport, Record and Super Record, magnesium wheels for Lamborghini, C-Record, Syncro and Ergopower, with the Croce d'Aune story marked as the legend it is.

For three decades, Campagnolo was the measure every other component maker was held against. The firm grew out of the back room of a hardware shop on Corso Padova in Vicenza, where Tullio Campagnolo turned a racer’s problem, the time lost fighting the fixings of a rear wheel, into a patent of 1933. From there the story runs through the rod gears that carried Gino Bartali to the 1948 Tour de France, the Gran Sport, the Record and Super Record groups, magnesium wheels for Lamborghini and De Tomaso, the Japanese challenge and Ergopower, to a minority investor in 2026 with the family still in control.
If not already exhausted, here is a chronological timeline of key patent, product, racing and corporate events at Campagnolo, spanning 1901 to 2026, drawn from the research for the accompanying Ebykr article “Tullio Campagnolo: The Legend, the Patents and the Record.” It rests on Campagnolo’s own catalogs in the Ebykr Catalog Archive, the patents themselves, the form Tullio filled in and signed for the Cavalieri del Lavoro and the Italian press of his lifetime.
A note on dates and legends. Patent dates are the Italian priority or filing dates printed on the patents. Campagnolo’s catalogs of about 1951 to No. 16 carry no printed date, so the dates given for them are estimates. The Croce d’Aune story, which the firm itself dated to 11 November 1927, is a founder’s parable rather than a documented event, and it is marked as legend where it appears.
