The Continental Grand Prix 4-Season is a resilient partner for tours, training and competitions that is not afraid of sun or rain. A tire with superior durability, equipped for every season.
Tires with DuraSkin sidewall protection must be able to insert properly. They are used under the most adverse conditions.
On messenger bikes, the tires slide along the curbs, on touring bikes they cross continents without chafing through, in racing they have to pass endurance tests like Paris-Roubaix.
The high-quality polyamide fabric reliably protects the side of the tire and prepares the tire for the worst.
Vectran is a synthetically produced high-tech fiber based on a natural model. Vectran is spun from the molten liquid polymer Vectra and processed into a multi-fiber yarn.
It has enormous tear resistance at the lowest possible weight, exactly the right properties to be used as a puncture protection insert in a top Continental tire.
