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.
