Gentullio (Tullio) Campagnolo (26 August 1901 – 3 February 1983) was an Italian racing cyclist and inventor. He patented the quick release skewer, and founded the revered Campagnolo bicycle component company. ==Timeline== In 1922 Campagnolo began his amateur cycling career. In 1930, he patented the cam mechanism quick-release skewer that became the standard for the industry, a design still used today. In 1933, the first quick release hubs were produced by Campagnolo. Also in 1933, he patented the sliding hub, dual seatstay rod-operated, back-pedal derailleur, ultimately known as the 'Cambio Corsa'. In 1949, he introduced the 'Gran Sport' twin-cable, parallelogram rear derailleur at the Milan trade show, the first modern derailleur. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Tullio Campagnolo」の詳細全文を読む スポンサード リンク
