CONTINENTAL Grand Prix 4 Season 700C x 25 road tyre Black, 700C x 25

Robust all-season tyre with worry-free puncture protection and best lifespan Solid companion for touring and training; doesnt shy away from sun or rain Excellent puncture protection thanks to double Vectran puncture protection insert Excellent grip and longevity along with robust DuraSkin side protection Technology: Vectran: The benchmark in puncture protection: - 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. DuraSkin: To roll with the punches: - 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.
