Features RaceSport Further details BlackChili It’s all about how you mix it With our unique tread compound, which is produced only in Germany, we have revolutionised the sport of cycling. With the legendary BlackChili Compound we have answered the eternal question of the best balance of grip and rolling resistance for cycling. Regular test wins confirm the measureable and noticeable advantages for the cyclist, established in the laboratory and on the road. The latest polymers as well as specially developed carbon black particles and filler materials guarantee unique performance Further details	Features PureGrip Compound The advanced new compound Based on activated silica compounds, this technology was originally intended as an performance level compound, but after intensive development at our Korbach Research and Development Department Facility, an advanced new compound with outstanding grip and cross-country properties was developed. This new rubber mix, given the self explanatory name “PureGrip”, is ranked just behind our BlackChili Compound and is being used in our performance products both in the road and mountain bike sectors. Whilst providing great grip, it is also long lasting and highly durable – both characteristics of Continental tires, which are exclusively manufactured in the factory in Hefei (Asia). NyTechBreaker Nylon fabric in the performance sector Our new NyTech Puncture Protection has been developed based on the proven Continental SafetySystem Breaker. Its nylon fabric makes it resistant to punctures and cuts like Kevlar reinforced high strength fibres, but offers lower rolling resistance and reduced weight. The NyTech breaker sits between the SafetySystem and the PolyX Breaker® as a more effective puncture protection casing in the performance sector.
