The Grand Prix 4-Season tyre can withstand it all thanks to its tough, extreme load bearing DuraSkin. In the Paris-Roubaix race, the riders with the fewest defects in their tyres after the "Hell of the North" are those equipped with DuraSkin tyres. High mileage, excellent grip on wet roads and at low temperatures makes the Grand Prix 4-Season stand out. The 23mm, 25mm, and 28mm version mean that the GrandPrix 4-Season can be adapted to various road qualities and comfort requirements. The double Vectran puncture protection insert raises the puncture protection to the highest level.
Vectran is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran is a liquid-crystalline polymer (LCP). Vectran is spun from the melted liquid polymer Vectra and processed further to a multi-strand thread. Spider silk like Vectran has an enormous tear resistance at a very low weight: Exactly the right properties to process into a premium Continental bicycle tyre as a puncture protection insert. A Vectran Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran Breaker does not adversely affect the rolling resistance.
Tyres with DuraSkin sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tyres skid along curbs; on touring bikes, they cross continents without wearing out. In racing cycling, they have to endure tough tests such as the Paris-Roubaix. The high-quality polyamide fabric protects the tyre casing against the worst conditions. These tyres stand out thanks to their brown sidewalls.
