GravelKing AC is the tyre that is comfortable in All Conditions, gravel or dirt. Building on the success of our GravelKing and GravelKing SK models, the AC version incorporates the same technology on top of a specially designed tread tailored to work best in all conditions. Specifically constructed long vertical knobs and a low profile design provide optimal transfer of muck while maintaining the ideal balance of rolling resistance and grip. With the low rolling resistance and long-lasting compound that features in all our ZSG (Zero Slip Grip) tyres, the GravelKing AC makes the perfect set-it and forget-it training tyre. This is the perfect tyre for the cyclist looking to expand their horizons and take a detour from the roads other tyres would limit them to.
