Friction shifters are the most reliable way to change gears, bar none, and these are the most advanced there's ever been. Dia-Compe use an evolution of SunTour's (minute of silence...) Power Ratchet system for nearly effortless shifts.
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.
