Panaracer: Building on the success of the GravelKing Slick and the GravelKing SK, both industry leading tyres in the gravel category. Panaracer has developed the next generation of the gravel tires in the GravelKing Semi Slick. Designed as a dryer condition or race day ready and fast rolling tyre, the Semi Slick is made for those riders who want to go fast while maintaining great control, traction and climbing prowess.The Semi Slick features an all new tread pattern consisting of a smooth diamond pattern centre with more aggressive side lugs. This tread pattern allows the rider to keep speed going into corners and maintain control throughout any transition a gravel ride could present. The GravelKing SS incorporates a supple 120 TPI casing with a nylon puncture resistant belt and Panaracer’s proprietary ZSG (Zero Slip Grip) compound. Note: 28c is not Tubeless compatible and must be run using tubes. TECHNOLOGIESZSG Natural CompoundOur own very 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-Alpha - Advanced Alpha Extra CordAX 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.
