Perfect for all types of cycling, from casual riding to serious racing. Continental's Grand Prix is known for the extremely long wear and puncture resistance afforded by 3 separate casing plies and its Black Chili compound. This tire brings the speed and low rolling resistance of the hallowed Grand Prix to your 20-inch wheels. Train on it, race on it, this is THE tire.
PolyX Breaker puncture protection brings Contintental's know-how of automobile tires into the bicycle market. Polyester fibers are woven tightly underneath the tread, and the resulting high fabric density helps resist flat tires. In addition, the rolling resistance is not adversely affected.
