Vittoria Corsa Speed Graphene Tubular 700x23 Black/Beige

Vittoria competition tubular benefit from millions of kilometers in racing experience. With the revolutionary G Isotech* compound and its leading Corespun casings it is unsurpassed in its competitive performance.
Super-fast tubular for pure speed events, profiled for the latest wide-aero rims.
•  The world’s fastest tire
•  Perfect for wide-aero rims
•  Very low rolling resistance
A tire’s tread compound, together with its casing, determines how well it holds the road. Vittoria tirelessly researches new compounds to give riders tires with even better performance, grip and longer life, in all conditions.
G Isotech®is Vittoria’s unique Graphene compound with revolutionary G *, as provided by technology partner Directa Plus. No compromise is necessary with this compound that is superior in speed (rolling resistance), grip, durability and wear resistance.
Isogrip®  is our reference-standard performance road compound with a focus on (wet) grip, improved year by year to keep it at the forefront of race technology.
4 Compounds (4C) is exclusively developed by Vittoria to achieve performance products without compromise. Vittoria 4C is a layering process, using 4 separate compounds in the same tread. The 4C  process offers unmatched versatility, by allowing for separate base and surface compounds, in both the center and side areas of the tread. Benefiting from the different properties of each compound, including the G Isotech*, their distribution is extensively tested to deliver the best products imaginable.
GRAPHENE EXPLAINED
Graphene is a revolutionary material in the form of a very thin, nearly transparent sheet of pure carbon. In its extreme form it is as thin as a single atom (1/1,000,000,000 th  of a meter). Vittoria uses Directa Plus Graphene called G , which is 2 to 8 atoms thin.
The benefits of Graphene:
1  - Enormous surface area: 1 gram = around 2,630 m that can facilitate any chemical process
2  - High mechanical resistance: approximately 200 times stronger than steel
3  - High thermal conductibility: more than 2 times that of a diamond
4  - Less density: is equal to half that of aluminum
5  - High elasticity: equal to 6 times that of steel
6  - High electrical conductibility, transparency, lightness, flexibility and mechanical resistance
Vittoria’s use of pristine Graphene
In short, Vittoria only uses the most premium form of Graphene (pristine) in order to unlock the greatest possible improvements for all our products.
This pristine Graphene Vittoria uses, in comparison to other forms of Graphene, offers 4 to 6 times greater improvements for the material it is applied to
(carbon for wheels, rubber for tires). Vittoria decided to also become a shareholder in Directa Plus to stay connected to their research and development competence, which is needed to be  a part of the most advanced material research.
Vittoria and Graphene: IT’S and no compromise With the application of Graphene in Vittoria wheels and tires, we have truly developed revolutionary products. Therefore, we have created a new product  range called the “Intelligent Tire System” (IT’S)
