Tyres with DuraSkin® sidewall protection have to be able to roll with the punches. They are used under the harshest conditions. On messenger bikes, the tyres 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 tyre casing against the worst conditions. These tyres stand out thanks to their brown sidewalls.
