The Grand Prix is not just any bicycle tire; it is the quintessential road bike tire and has stood for quality and performance for years. The standards that Continental has set with this tire continue to influence many developments in the road bike tire segment. The new generation of the Grand Prix aims to set new benchmarks as well. Continental's enduring favorite leads the trend towards wider tires. Wider tires roll more easily, offer higher mileage, and provide more comfort and grip. The GP comes in a main size of 24 mm, making it wide enough to combine all the constructive features of a wide tire with the slimness and lightness of a narrow racer.
