Building on the success of the standard Gravelking and the Gravelking SK both industry leading tires in the gravel category Panaracer has developed the next generation of the gravel tires in the Gravelking SS and SS+. Designed as a dryer condition, race day ready and fast rolling tire, the SS/SS+ was made for those riders who want to go fast while maintaining great control, traction and climbing prowess. The SS and SS+ feature 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 120 TPI casing with a nylon puncture resistant belt and Panaracer s proprietary ZSG (Zero Slip Grip) compound. The SS+ uses the same build as the SS but adds a bead-to-bead layer of Panaracer s ProTite puncture material for even more protection against tread and sidewall cuts for those extra demanding courses or rides with sharp flint rock.
