About Vittoria Graphene Corsa Tubular Tyre
The professional-level Vittoria Graphene Corsa Tubular Tyre is the choice for millions of racing enthusiasts worldwide
The Vittoria Graphene Corsa Tubular is the world’s best-known and most-used cotton tubular tyre because it's fast, flexible, reliable and proven by millions of race kilometers. Boasting Kevlar-reinforced Corespun K construction for increased sidewall protection, the Corsa Tubular has a 320 thread per inch (TPI) count to ensure a supple ride whilst remaining durable for all conditions encountered during racing.
The tread is glued by hand on the casing, a labor-intensive process exclusively used for premium tubulars. The tubular tire’s round profile gives it several advantages over any clincher. Cornering is more predictable and shock absorption is superior. Also, the broad glued interface to the rim spreads shock loads more evenly through the casing, letting the tire absorb big hits without deflecting or slowing down.
Vittoria's Corsa Tubular has fantastic speed, grip, durability and puncture protection properties thanks to its 4 compound (4C) tread. 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.
The construction of the Vittoria Graphene Corsa Tubular has:
* Wear-resistant tread has very low rolling resistance
* Vittoria’s optimized compounds (4C) with G+ Isotech for the best combination of speed and grip
* Breaker for excellent flat protection
* A 320 TPI Corespun K casing
* Latex inner tube
* Handmade from stitching to tread lamination
G+ Isotech Compound: 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.
What is Graphene?
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 (1/1,000,000,000th of a meter). Vittoria uses Directa Plus Graphene called G+, which is 2 to 8 atoms thin. With the application of Graphene in Vittoria wheels and tyres, Vittoria has developed revolutionary products and created a new product range called 'Intelligent Tire System' (ITS).
ITS compounds become harder and softer, depending on the needs of the rider. If the tyre is rolling straight, the rubber is at its hardest and offers low rolling resistance. If the rider breaks, accelerates or corners, the compounds soften and offer significantly more grip.
Prior to the advanced development of Graphene, there was always the requirement of choosing between optimizing, or aiming at, 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 are now reaching their maximum possibilities.
The benefits of Graphene include:
* Enormous surface area: 1 gram = around 2,630 m2 that can facilitate any chemical process
* High mechanical resistance: approximately 200 times stronger than steel
* High thermal conductibility: more than 2 times that of a diamond
* Less density: is equal to half that of aluminium
* High elasticity: equal to 6 times that of steel
* High electrical conductibility, transparency, lightness, flexibility and mechanical resistance
