For decades Clement has been supporting professional road racers with its high end quality products, mainly tubular, for which it became market leader soon. Originally a family business, Clement became part of the Italian Pirelli group in the 80’s. The Clement factory was moved to Thailand.

 Later on, Pirelli decided to divest its holding in the bicycle tire business and the production was inevitably stopped for some years.

 Brewo, an Italian sports trading Company, found immediately after the end of the Second World War, believed that the tradition and know-how should not be lost. For many years exclusive worldwide trading Company for Clement products, they did not want to loose the experience that had been acquired in years of steady manufacturing of the elite level bicycle tire products that had defined the Clement bicycle tire brand.

 Brewo took over the Clement company, bought the heritage, updated the technology and materials to keep pace with changing markets and requirements, re-opened the factory gathering together the largest number of technicians with experience in tubular tire manufacturing.

 Here you see a co-advertising of Clement tubulars inside an italian sports newspaper: Clement has been sponsoring pro teams since the very beginning of professional cyclism, in this case in cooperation with the historical italian frame builder "Wilier".
 

 It was the 1999. The brand name “Challenge” was chosen by Brewo for the renaissance of the Clement tires. Challenge name emphasizes the spirit of the new Company and reminds everyone of what a big challenge it is to manufacture and provide very exclusive and high-end quality bicycle products.

 This is the Clement pricelist front page, dated January 31st 1983, in Italian, showing some tire model names still available in the Challenge range like "Criterium", "Criterium seta" and "Grifo".
 

 HAND MADE TUBULARS, tradition and quality for performance.

 Challenge has mainly become famous for the manufacturing of the hand made bicycle tubular tires. These tubular tires, thanks to the sophisticated hand-made processes involved, have technical features that are extremely difficult to reproduce in mass-manufacturing.

 Challenge has been introducing the best compounds and manufacturing processes to keep ahead of the ever-increasing demand of the discriminating bicycle professionals and high-end enthusiasts.
 

 The benefits of hand made tubular are very well known to all professional riders. Riding comfort and quality together, with very low rolling resistance. These tires are completely handmade and feature 100% polyester casings at very high thread counts. The result is a tire with very supple feel for increased comfort, better cornering and improved road feel. These are the highest standard in high performance tires.
