Thanks to the legendary BlackChili compound, they were able to answer the eternal question of grip or long-term rolling resistance. Regular testing proves measurable and noticeable benefits for drivers in the lab and on the road. The latest polymers as well as carbon black particles and specially developed fillers guarantee a unique performance. Active comfort The revolutionary approach to road cycling. Integrated into the structure of the tire, Active Comfort technology absorbs shock and provides a superior driving experience. LazerGrip You become one with the road. The laser tread pattern provides better grip when cornering. Vectran Vectran is a high-tech synthetic fiber with a natural pattern. Like spider silk, Vectran is a polymer of liquid crystals (LCP). Vectran is woven from the Vectra polymer and reworked into a multi-fiber network. Vectran fiber, like spider silk, has tremendous tear resistance at very low weight. This Continental tire has all the characteristics necessary to reach the highest level in terms of puncture protection. Vectran Breaker protection is lighter, more flexible and protects your tire from cuts on the same level as Nylon-Breaker protection. The Vectran Breaker does not influence the rolling resistance.
