Part no. ETRTO Dimension Type g PSI 0100173 23-622 700 x 23C Clincher 230 110-120 0100175 25-622 700 x 25C Clincher 235 95-120 0101105 28-622 700 x 28C Clincher 295 95-115 Vectran™ is spun from liquid crystal-polymer. This way a thermoplastic, multiple-thread yarn is created. As a comparison: This partially crystalline fabric is more cut-resistant than aramide and its tensile strength is five times higher than that of steel. A Vectran™ Breaker is lighter, more flexible and effective against cuts than a comparable nylon breaker. Without affecting rolling resistance.  Tires with DuraSkin® sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tires skid along curbs; on touring bikes, they cross continents without wearing out. In racing cycling, they have to endure tough tests such as the Paris-Roubaix. The high-quality polyamide fabric protects the tire casing against the worst conditions. These tires stand out thanks to their brown sidewalls.
