TECHNOLOGIES
ZSG Gravel Compound
The all new ZSG GRAVEL compound is precisely formulated from our exclusive ZSG (Zero Slip Grip) material. Crafted specifically for gravel terrain, this unique compound guarantees exceptional resilience against temperature variations, delivering consistent rubber performance from freezing cold to sweltering heat. Engineered to excel on both gravel and tarmac surfaces, it boasts lower rolling resistance while maintaining optimal grip levels, ensuring uncompromised performance in diverse conditions.
TuffTex Casing
TuffTex is a revolutionary structure crafted exclusively for GravelKing tyres. With its supple, high thread count casing, TuffTex ensures durability while boasting precisely engineered bead-to-bead puncture protection. This unique blend guarantees an exceptionally smooth ride, offering the lowest rolling resistance available in a GravelKing tyre.
BeadLock
Our meticulously redesigned bead has been engineered to accommodate an extensive array of rim types, encompassing both hookless and clincher varieties. With its advanced engineering, tyre mounting becomes a seamless process, often achievable with just a standard floor pump, ensuring effortless adaptability and superior performance on any terrain. BeadLock is specifically engineered precisely for the evolving gravel market landscape.
