Corsa PRO is the most advanced cotton tyre ever made, delivering unmatched pro-level racing performance. With Corsa PRO, Vittoria engineers succeeded in incorporating the rubber tyre tread with the cotton casing by using newly developed vulcanization processes. Corsa PRO 320 TPI cotton casing the finest available in the market provides the suppleness, flexibility and comfort pro-riders are used to, now served in an even more flexible, aerodynamic and reliable tyre construction.
Cotton casing – cotton threads have the thinnest structure in the tyre casing technology, with benefits related to lightweight and flexibility. This characteristic allows the development of cas ings with a higher number of threads per inch, up to 320 TPI, for the top-quality cotton casings. This property allows the tyre to conform closer to the road´s surface, providing a smoother ride, easier rolling, and better grip. In order to boost the overall strength of the casing, Vittoria uses Corespun yarn, which is a particular type of yarn made by cotton and aramid fibres combined.
About GRAPHENE technology in tires – Graphene is the innovative material used by Vittoria in compounds to improve performance of tires. Graphene is the world´s thinnest material but at the same time one of the strongest ever used for consumer applications. Made of a single hexagonal-shape layer of carbon atoms, Graphene interacts with rubber by filling the space in between the rubber molecules. It acts like a magnet, making rubber molecules closer to one another and improving the overall rubber structure. Graphene´s main properties are related to: Thinness / Strength / Flexibility / Lightness.
Graphene + Silica – Silica, added to Graphene, boosts the tyre performance and consistently provides longer mileage and grip, further empowering the riding experience. Furthermore, this new compound combination reduces tyre weight and increases the performance gains. Vittoria´s lab tests have proven the new combination of Graphene and Silica to provide following performance gains, compared to a normal compound:
+9% in speed/rolling performance
+32% in grip
+21% in puncture resistance
Longer mileage and tyres wear life
