Continental's Grand Prix is a superb tire known for its extremely long wear, cornering grip, and puncture resistance thanks to its three separate casing plies, Black Chili rubber compound and built-in, road debris defying PolyX Breaker. It's Conti's classic, lightweight folding clincher that's suitable for your everyday training wheels as well as your race wheels.
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.
