The right choice for strong performance in urban areas and for touring.

With our PolyX Breaker®, we bring our car expertise to the bicycle tire segment: Polyester has been successfully used in car tires for years and has been tested and tried many times. The extremely resistant polyester fiber is woven tightly crosswise. In this way, the breaker is more resistant to foreign objects and thus to punctures. The PolyX Breaker® does not affect rolling resistance.
