The S-Works Turbo tire sets the standard for how a performance road tire should be. It's fast light and supple. It features our GRIPTONå¨ compound with extremely low rolling resistance and superior cornering traction that helped win Worlds on a rain-slicked attack. So no matter if you're climbing with the best of them or descending like a rider possessed this is the tire for anyone who demands nothing short of the best.
