The venerable CG tire returns in its third iteration and proves to be the best version yet. Upgrades from the previous edition include Vittoria's ISOgrip compound coupled with some refinments to the GC file tread pattern. Both of which improve traction, lower rolling resistance and lengthen tread wear.
The CGs are a perfect choice for inclement weather, rough terrain, cobbles and dirt. The wider 25mm width better protects wheels and provides more comfort, especially on uneven road surfaces.
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 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 CG 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.
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.
