Vittoria Open Corsa EVO SC Tire
The Corsa EVO SC Servizio Corsa tire is the Reparto Course or race room version of the standard Corsa Evo CX Tire.
These two tires use the same design and construction process, with two exceptions. First, the SC tire uses the ISOgrip SC tread pattern which is has a lower profile. It has thin directional strips in the center for added traction and siping. On each side of the center is an opposing, fine file herringbone pattern and beyond that it is slick tread on the very ends. The second and more visually noticeable difference: the sidewalls are a natural-tan color. This is Vittoria's traditional Para sidewall and offers a super smooth ride quality. That being said, it is not quite as durable as the standard CX sidewall.
At the heart of the tire is the Corespun 320 tpi casing. The casing is made from a poly-cotton blend that has Kevlar woven in to add durability. Kevlar in thread form is soft and flexible, so while offering added protection, it will not adversely affect the handling. The huge thread count of these materials are tightly woven and end up giving the rider near perfect road feedback and a firm but resilient cornering feel.
The ISOgrip tread compound is soft and sticky like it should be on a true race tire. It is constructed from a natural rubber blend that offers the best grip and lowest rolling resistance we have seen from a Vittoria tire to date. The cost of performance is wear time. The tread is designed to perform, not last forever - this is not a high mileage compound.
Sandwiched between the tread and casing is Vittoria's proprietary PRB 2.0 protective layer. This strip helps protect the casing from glass shards and general road debris that can wedge into the tread and cause flatting.
In summary, the Corsa SC tire was designed with input from Pro Tour riders. As you would imagine, this input was for a tire that was super grippy, rolls fast and has perfect road feel. Nowhere on their wish list was for their dream tire to be durable and long lasting. This is a professional race tire, so if you want the ultimate in performance and a true world class tire is what you seek, look no further.

Combine these tires with latex tubes and you'll never see the need for tubulars. Perfect road feel, all the high-frequency vibration goes away, and that comes with unreal grip in corners and on descents.
