The Panaracer GravelKing Slick R Line is designed for cyclists seeking maximum puncture protection. It is the perfect choice for those who want to ride on the most challenging routes. The Gravelking Slick has been equipped with the latest Panaracer technologies, including the Zero Slip Grip Gravel compound, TuffTex-R casing, and BeadLock technology. This next-generation tire surpasses its predecessor with unmatched performance, low rolling resistance, puncture resistance, and an extremely smooth ride. The rubber compound boasts a formulation of specific materials for gravel, starting with Panaracer's patented ZSG (Zero Slip Grip) material. ZSG ensures remarkable 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. The TuffTex-R casing is the smoothest and lightest that Panaracer has ever developed. The casing offers a unique combination of puncture protection, smoothness, and low rolling resistance. 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. Note: For installation, Tubeless Ready tires require compatible Tubeless technology rims/wheels, Tubeless valves, Tubeless rim tape, and sealant. Puncture sealant is not necessary for UST Tubeless tires, but is recommended due to increased puncture protection. Installing Tubeless tires is not always easy and should only be performed by qualified personnel.
