A new addition to the Panaracer range is called GravelKing SS+. It uses the same construction as the SS, but adds a protective layer of Panaracer ProTite material from lug to lug for even more protection against tread and sidewall cuts on extra-tough trails full of sharp rocks.the new tyre rolls faster thanks to the fast rolling compound and is particularly useful on drier ground or in racing. It is designed for all riders who want a fast tire while maintaining great control and traction with above average protection. The abbreviation SS in the name stands for an all-new tread pattern, which consists of a smoother centre with a diamond pattern and more aggressive side lugs. You don't have to slow down in corners and the tyre offers great control on any surface, even in a straight line. The GravelKing SS features a puncture-resistant nylon belt and a special ZSG (Zero Slip Grip) compound. Tubeless Compatible.
