More aggressive than the original GravelKing, the GravelKing SK's aggressive knobs, ZSG Natural rubber compound, puncture protection breaker and AX-α special low rolling resistance casing make the Gravelking a go-anywhere tire.
The Cannonball was designed to be a first-choice gravel racing tire. The directional, tight-knit center tread efficiently sheds dirt and debris to decrease rolling resistance, while the side knobs provide effective cornering traction.
