In the research and development laboratories for Continental bicycle tyres in Korbach, Germany, the staff and engineers have been looking for the solution to one of the fundamental problems of tyre construction: The running properties of the rubber compound of a tyre are largely determined by three interacting factors: static friction (grip), rolling resistance and mileage. The dilemma is that you improve one of these factors, and in turn, worsen at least one other factor. A tyre with maximum grip wears out faster and rolls slower. If one makes the tyre faster or more durable, then this in turn reduces grip. With the then current highest standard of compound technology, the Activated Silica Compound having already reached a very high standard of compromise, our developers wanted to take compounding to an even higher level. This lead them to venture into new territory, exploring new ways so that in 2005 they made a breakthrough in mixing technology, the first steps to what is now known as BlackChili. This revolutionary compound is based on the latest findings on polymer and other raw material research.
The benchmark in puncture protection
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 the 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 bicycle 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.
