The CST Pika Tire is bred for gravel adventures and dirt road cross trekking! This tire has ramped center knobs for a smooth, fast ride, while the shoulder tread features U-shaped knobs for corner traction. The Pika is made of Dual Compound which are two compounds comprised of a harder, longer lasting center and a softer gripping corner. The Pika also features Exceptional Puncture Safety that offers an added layer of proprietary rubberized poly-fiber material between the tread and the casing to help prevent punctures. Overall when looking for a true upgrade, there is no better choice than the CST Pika!
