The toughest 'performance' tyre on the market

Thanks to its DuraSkin™ anti-tear fabric and two Vectran anti puncture strips, the Grand Prix 4-Season holds up under extreme conditions. In the Paris- Roubaix race, the "Hell of the North", cyclists equipped with DuraSkin™ enhanced tyres have the fewest tyre related problems during the race. Incorporating our special wear resistant carbon compound, the tyre is characterized by very good mileage performance as well as excellent adhesion on wet roads and at low temperatures.

With 23, 25, 28 & 32mm versions, the Grand Prix 4-Season makes it possible to select the right tyre for various road qualities, type of bike and comfort requirements. A double Vectran™ Breaker belt under the tread raises the puncture and cut protection to the highest level available on the market. Featuring a total of five plies beneath the tread, plus a sixth Duraskin layer, it's ideal for rough sportives and general bad road conditions.

"Puncture resistance is way above that offered by the fastest race tyres yet rolling resistance feels pretty similar. Grip is excellent, particularly in the wet."
