The Panaracer GravelKing Slick+ is intended for cyclists seeking maximum puncture protection. It is the perfect choice for those who want to ride on more challenging routes. The Gravelking Slick+ has been equipped with the latest Panaracer technologies, including the Zero Slip Grip Gravel compound, the robust TuffTex+ casing, and BeadLock technology. This next-generation tire surpasses its predecessor with unparalleled performance, low rolling resistance, puncture resistance, and an extremely smooth ride. The rubber compound boasts a formulation of specific materials for gravel, starting with the patented Panaracer 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. TuffTex+ is a revolutionary structure developed exclusively for GravelKing tires. A soft casing with excellent puncture protection. The Plus version even features two layers of TuffTex for increased protection, even in harsh conditions. 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 produced in Japan by experienced technicians using the most advanced materials. This ensures exceptional manufacturing quality and performance. Note: For installation, Tubeless Ready tires require rims/wheels compatible with Tubeless technology, Tubeless valves, Tubeless rim tape, and sealant. Puncture prevention liquid is not necessary for UST Tubeless tires, but is recommended due to the increased protection against punctures. Installation of Tubeless tires is not always easy and should only be carried out by qualified personnel.
