At the heart of the Corsa CX III 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 Vittoria's ISOgrip compound which Vittoria considers their new reference for a high-performance road compound. It offers more grip and less rolling resistance than any prior comound Vittoria has relaesed. 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.
We do not accept for return tubular tires that have been glued to a rim.
