Vittoria Corsa G Tubular Tire
What does the "G+" indicate in the Vittoria Corsa G+ Tubular Tire? For many cyclists Vittoria is thought of as a tire maker with more traditional values and technology. While that description captures the inspiration of the company- in traditional design and values, remember that grip, speed, and overall ride qualities are traditional to serious cyclists. And some traditional concepts, such as wound cotton casings and rubber that offers exceptional grip and feel, have been demonstrated to ensure the highest ride qualities and all-conditions control that racing cyclists live for. That kind of tradition is one we love. Even with those truths out in the open, it has never been correct to say that Vittoria isn't at the cutting edge. The ultra-high threads per inch counts seen today on several company's tires comes directly from Vittoria's focus on manufacturing innovation. The Corespun process of creating casings and linings has also been ahead of the game, and in rubber compounding alone, Vittoria has driven the industry with the properties it's IsoGrip multi-compound formula. As if that isn't enough, and it isn't for such an innovative company, Vittoria now introduces the integration of super strong, amazingly lightweight, 2-8 carbon atom thickness graphene (G+ Isotech) into IsoGrip3 to deliver the fastest, most puncture resistant, race-level tires the company, or basically any manufacturer, has ever produced.
The speed claim does not come from Vittoria. A internationally acclaimed testing lab in Finland, Wheel Energy, has measured the Open Corsa G+ tire as having 19% less rolling resistance than the same tire without graphene, as well as less than any other tire tested. As for puncture resistance, there are some impressive videos online showing how the inflated tire can be ridden over nails without puncture. Even if you take the numbers and testing with a skeptics viewpoint, it is clear that the addition of pristine graphene into the new combination of compounds has produced marked results. 4 Compounds (4C) has been exclusively developed by Vittoria to achieve performance 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. The different properties of each compound, including G+ Isotech, deliver impressive benefits to the cyclist. This technology is incredibly new, so real world experience by every day cyclists is minimal, but pro teams that have been testing the tires have been impressed. Graphene is a graphite derivative that is currently being tested for use in numerous and diverse fields, from computer chip design through major construction industries. It is the incredible strength to weight ratio and the impervious nature of such a thin material inspires the engineering world, and for cyclists that means you will be seeing graphene in more than just Vittoria's tires and wheels.
The Corsa G+ Tubular is built on the Corespun K 320tpi aramid-enhanced cotton casing with Kevlar that Vittoria has used for their previous generation tubular tires. The PRB 2.0 Corespun breaker is also carried over, matching perfectly with the suppleness of the perfect casing and latex inner tube for an incredible ride quality. The new straight channel 4C rubber tread layer is actually quite thin, with the proven low rolling resistance and puncture protection, and excellent grip in all conditions. Rider feedback indicates that a few rides on dry pavement enhances wet grip, a not uncommon reality. The 700x23 tire weighs just 265 grams with the enhanced rolling speed and wet or dry grip.
Innovation, excellence, and attention to detail are the hallmarks of Vittoria's tire tradition. Cyclists choose the tires ultimately for varying combinations of speed, grip, ride quality, and protection. The Corsa G+ is the all-rounder, the tire that can be raced in any condition, when speed, handling, and grip are all required. Ride the tradition of excellence and technology with this graphene-infused high performance tubular tire from Vittoria.
