Tehnologija VectranBreaker
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 tire 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.
Smjesa Black Chilli
The crucial balance. The rolling properties of the rubber compound of a tyre are primarily determined by three interacting factors – stiction [grip], rolling resistance and mileage [longevity] . The dilemma: If you improve any of these factors it can have a detrimental effect on at least one of the others. A tyre with maximum grip wears quicker and rolls more slowly. If you then make a tyre roll faster and more durable, grip, in turn, is reduced.
