The Panaracer GravelKing SS builds on the success of the established GravelKing and Gravelking SK models. Thanks to the fast rolling compound, this tire rolls faster and is especially useful on drier ground or during races. It is designed for all riders who want a fast tire while maintaining great control and traction. 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.
