Handmade Tubulars with the strong racing heritage to back them up, Challenge is the current iteration of Clement, who were a mainstay in the Pro Peloton of yesteryear. Clement tires have seen victories at the Tour, Vuelta, Giro and numerous Spring Classics.
Challenge is renowned for their manufacturing of hand made bicycle tubular tires. These tubular tires, thanks to the sophisticated handmade 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. The result is a tire with extremely supple feel for increased comfort, better cornering and improved feedback. These are the highest standard in performance tires. The Seta Extra differs from the rest of the Criterium line in its use of a silk rather than polyester casing.
