Vectran is a synthetically manufactured hightech fibre from a natural model. Like spider silk, Vectran is a liquidcrystalline polymer (LCP). Vectran is spun from the melted liquid polymer Vectra and processed further to a multistrand 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.
