The right tyre when it comes to getting down to business on the road. The perfect choice when it comes to tough performance in urban terrain and touring. PolyX BreakerWith the PolyX Breaker, they bring car know-how to the bicycle tyre segment: polyester has been used successfully in car tyres for years and has proven itself many times over. The extremely resistant polyester fibre is tightly woven crosswise. This achieves a very high fabric density, which makes the Breaker not only resistant to foreign bodies, but also particularly resistant to punctures. The rolling resistance is also not negatively influenced by the PolyX Breaker. DuraSkinTyres with DuraSkin sidewall protection have to be able to take a beating. They are used in the most adverse conditions. On messenger bikes the tyres slide along kerbs, on touring bikes they cross continents without chafing, in racing they have to pass endurance tests like Paris-Roubaix. The high-quality polyamide fabric reliably protects the sidewall of the tyre and arms the tyre for the extreme. These tyres stand out from the crowd thanks to their brown sidewall.
