Product technical specifications

TECHNOLOGY

Tubular: The tread of Vittoria cotton tubulars is glued by hand on the casing. Tubular construction allows for puncture protection and reduced rolling resistance. Tubular is the tire construction used by professional riders.

Cotton Casing: Vittoria is the first and still number one producer of cotton tires. As of today, only Vittoria best road tires are made out of cotton, a light material which makes the casing very flexible. Cotton threads have the thinnest structure in the tire casing technology, with benefits related to lightweight and flexibility. This characteristic allows to develop casings with a higher number of threads per inch, up to 320 TPI for the top-quality cotton casings. This property allows the tire to conform closer to the road’s surface, providing a smoother ride, easier rolling, and better grip. In order to boost the overall strength of the casing, Vittoria uses Cotton yarn, which is a particular type of yarn made by cotton and aramid fibres combined. Vittoria’s Cotton casing is used for Pro Competition products, proven by multiple victories as in Tour de France, Giro d’Italia, Vuelta a Espa?a, Classics, World Championships, European Championships and Olympic Games.
