The gp5000 uses these rubbers with special nanometric carbon soot particles, which are optimised in shape and surface properties for best uses for the intended tyre. Tyres with blackchili compound reach an unprecedented level of performance. Compared to the previous best activated silica compound, blackchili tyres have 26% less rolling resistance, a 30% higher friction value grip and a 5% increase in mileage.vectran 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 ndash 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.active comfort technology the revolutionary approach in cycling.
