The Vittoria Rubino Pro Endurance G Plus Clincher Tire pairs tough flat protection across the side walls and center tread, an all-weather tread design, and a long wearing, grippy compound to tackle whatever nature throws your way. Built to last over long winter training miles and inclement early season races, this tire features exceptional all-weather grip, will handle sub-freezing temperatures with ease, and rolls fast over the toughest roads. Vittoria constructs the Rubino Pro Endurance with a triple compound designed to provide a balance of durability, flat protection, fast rolling speed, and solid cornering grip in both dry and wet conditions. It also incorporates the revolutionary G+ Isotech compound, utilizing graphene within the triple compound mix to increase elasticity, reduce rolling resistance and overall weight, increase durability, and improve grip in wet weather compared to tires without the G+ Isotech compound. This tire is fast and supple regardless of weather and will conquer the roughest of roads with the smoothness of a racing tire and the durability of a training tire.
