Challenge Tyres are well know, because they are hand made Italian race tyres.

Challenge has to called their Tyres open tubular. This means that the tyre is comfortabel and very flexibel and made for clincher rims.

Cyclocross banden van Challenge zijn zeer bekend. Met name de Grifo.

1. Tread
Made from natural rubbers. Challenge's treads are hand glued with temperature-sensitive latex rubber cement, not bonded to a casing as in a vulcanized tire. The process keeps natural rubber flexible, so the tire is more likely to deform around bumps instead of bouncing off, reducing rider fatigue.

2. Casing
Sheets of polyester and cotton or silk threads—up to 1,000 per inch—are folded diagonally back on themselves two or three times so threads lie on a bias (In opposing directions) to allow the casing to flex more easily.

3. Inner Tube
Tire casing is stitched into a hoop around a seamless latex inner tube. Roll over something sharp, and the latex tube is more likely to flex than puncture. If you do flat, a tubular stays on your rim as you brake and stop. A clincher is much more likely to fly off your rim.

4. Coating
The casing's sheets are infused with lightweight latex to fill interstitial spaces. High-thread-count tires are supple. With the flexible tread and tube, they grip, minimize vibration, and reduce skidding better than harder vulcanized tires.

5. Base Tape
Like a rim strip between spoke and tube, an inner, cloth base tape prevents casing stitches from rubbing a hole in the tube as you ride. An outer base tape protects stitches from rim rub and gives glue a textured surface to adhere to.
