Continental 0100146 Grand Prix 20 x 1-1/8 Urban Specialty Tire with Black Chili has become a brand of its own in cycling circles worldwide. The Grand Prix is the classic tire marking quality and performance. Not unlike its predecessor, this generation is eager to change traditional standards. The new Grand Prix marks the trend toward wider tires in performance cycling. Wider tires roll easier, yield higher mileage and offer more comfort and grip, therefore the new Grand Prix profile is 24mm. Wide enough to exploit the advantages of wider tires, but still light and slim enough to improve the performance of any racing machine. The Grand Prix features Black Chili compound for extra grip in all conditions and Poly-X breaker for puncture protection. Specs: Weight - 205 grams; Recommended PSI - 95; Maximum PSI - 120; PU - 10.
