The professional-level Vittoria Graphene Corsa Speed Tubular Tyre is made to gain the maximum advantage from your tyres

The Vittoria Graphene Corsa Speed Tubular is the choice for racers when it comes to events where speed is the priority. Boasting Kevlar-reinforced Corespun K construction for increased sidewall protection, the Corsa Tubular Speed has a 320 thread per inch (TPI) count to ensure a supple ride whilst remaining durable for all conditions encountered during racing. Profiled for the latest wide-aero rims, the Vittoria Graphene Corsa Speed Tubular can be used on wider track wheelsets that have become more common throughout professional and amateur racing ranks.

The tread is glued by hand on the casing, a labor-intensive process exclusively used for premium tubulars. The tubular tyre’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 Speed 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.

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
