Vittoria Open Corsa EVO CX II Tire
The Corsa EVO CX tire is Vittoria's top offering in a clincher tire and is as close as you can get to a tubular ride quality in a clincher tire. The magical ride quality is due to the combination of the super supple 320 tpi casing and the enhanced-rubber compound. The Corsa EVO CX offers a feel for the road unmatched by any other clincher tire available on the market.
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. In thread form, Kevlar 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 tread is a dual compound with a firm/harder durameter center for fast rolling and softer durameter compound on the sides for grip. The Corsa EVO CX tread is constructed from natural rubber that is enhanced with Silica and Kevlar SiO². These 'additives' greatly enhance the ride characteristics - the Silica reduces rolling resistance while the Kevlar increases wear time and durability. The tread pattern is Vittoria's venerable CX fine file design. It has been around for decades and is a proven performer in all conditions - dry or wet.
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.
The Corsa EVO CX is not going to go down in history as the most durable or best training tire produced, but it was't designed for that purpose. It was developed to offer the best performance without compromise. If ride quality, unmatched grip and low rolling resistance is what your after, this tire is a winner.
