Vectran (TM) Breaker Vectran is a synthetically manufactured high-tech fibre from a natural model. Like spider silk, Vectran is a liquid-crystalline polymer (LCP). Vectran is spun from melted liquid polymer Vectra and processed further to a multi-strand thread.

Spider silk, like Vectran, has an enormous tear resistance at a very low weight - exactly the right properties to process into a premium Continental bike tyre as a puncture protection insert. A Vectran Breaker is lighter, more flexible and protects more effectively against cuts than the comparable nylon breaker. Vectran Breaker does not adversely affect the rolling resistance.

Black Chili Compound Continental refine newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. They use these rubbers with special nanometric carbon soot particles, which are optimized in shape and surface properties for best uses for the intended tyre. Black Chili Compound reaches an unprecedented of performance.

Tyres with Black Chili Compound reach an unprecedented level of performance. Compared to the previous best Activated Silica Compound, Black Chili tyres have 26% less rolling resistance, a 30 % higher friction value (grip) and a 5 % increase in mileage.
