The SS features an all-new tread pattern consisting of a smoother, diamond pattern center 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 126 TPI casing with a nylon puncture resistant belt and Panaracer’s proprietary ZSG (Zero Slip Grip) compound.
