The Panaracer GravelKing Semi Slick was developed for cyclists who want to go fast without sacrificing control, traction, and climbing characteristics. The Gravelking Semi Slick features the latest Panaracer technologies, including the Zero Slip Grip Gravel compound, TuffTex casing, and BeadLock technology. This tire is ideal for fast racing on dry gravel roads. The rubber compound boasts a formulation of specific materials for gravel, starting with Panaracer's patented ZSG (Zero Slip Grip) material. ZSG ensures excellent resistance to temperature and weather conditions and offers low rolling resistance and consistent grip across a wide range of temperatures, from near-freezing to scorching heat. TuffTex is a revolutionary structure developed exclusively for GravelKing tires. Thanks to its soft casing and high thread count, TuffTex ensures long-lasting durability and provides precise puncture protection. This unique compound guarantees an exceptionally smooth ride and offers the lowest possible rolling resistance on a GravelKing tire. BeadLock: The tire bead fits various rims (including hookless ones) and in most cases can be mounted with a standard floor pump. Panaracer Gravelking tires are manufactured in Japan by experienced technicians using the most advanced materials. This ensures exceptional production quality and performance.
