Through recent years thorough research and development, Vittoria tire technology has become the industry leader. But technology is not all about us. But dont forget that riding itself matters. Go ahead and start a great riding with us. Graphene is a revolutionary material made of ultra-thin, ultra-clear sheets of pure carbon. The layer is thin equivalent to one atomic (1/1,000,000,000,000,000 thinness per meter). Vittoria uses the same thin graphene as 2 to 8 atoms named "G+" by Directa Plus. Graphene Characteristics: 1 Surface Area Width: Covers up to 2,630 sq ft (2,630 sq m) per gram. 2 Resistance: Approximately 200 times stronger than iron and 3 high heat conductivity: High heat conductivity over 2 times higher than diamond heat conductivity 4 Low Specific Gravity: 1/2 of aluminum 5 times higher elasticity: 6 times higher elasticity, high elasticity, high elasticity, transparency, light than iron, high elasticity.
