Would you like to expand your cycling horizon? This also applies to roads that are not suitable for normal road tyres. The GravelKing tyre solves this problem. Four widths to suit every taste. A natural rubber compound, high-quality puncture protection and a special low rolling resistance tread make GravelKing an all-round tyre.ZSG (Zero Slip Grip) Natural CompoundThis compound has the same low rolling resistance as the premium compound. Its enhanced wear resistance makes it perfect for a long lasting training tire with an excellent ride. AX-α (Advanced Extra Alpha Cord)AX technology uses extremely narrow cord which is weaved at a super high density into the casing for lightness and flexibility. This increased density improves resistance to cuts and abrasions. Anti-Flat CasingAnti-puncture reinforcement throughout the tire strengthens resistance to cuts and pinch flats. Tubeless Compatible (TLC)Tires with the "Tubeless compatible" feature can optionally be driven without a tube sealing milk.
