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.
