Vittoria Rubino Pro Control G Road Tire. The Vittoria Rubino Pro Control G road tire is a new addition to the renowned Rubino range and is designed for top performance in the worst road conditions. Through a variety of technologies Vittoria has engineered a tire that delivers strength and resilience while still providing suppleness and performance. First and foremost is the utilization of Graphene represented by the G in the tire's name. The Graphene in Vittoria's G Isotech tread compound is a nearly transparent sheet of pure carbon mere atoms thick. Prior to the development of Graphene, there was always the limitation of choosing between optimizing for speed, grip, durability and puncture protection. Effectively, the introduction of Graphene allows for natural material barriers of rubber to be removed, which means that there is no longer the need for such compromises between speed, grip, durability and puncture resistance. All these features now co exist in a single, Rubino Pro Control G tire. Additionally, the Rubino Pro Control G features Vittoria's 3 Compounds 3C technology which is a layering process that uses three separate compounds in the same tread. The 3C process combines three compounds for superb puncturecut resistance, grip, as well as suppleness. Featuring a nylon casing, the Rubino Pro Control takes advantage of the material's considerable strength by adding an extra casing layer for flexible protection over the most demanding conditions. The casing is also designed to handle riding in freezing conditions with technology that maintains suppleness for better traction and control. And with a tread compound built for high mileage riding, the Rubino Pro Control G is a perfect choice for rough, inclement conditions.
