Continental Grand Prix 4000s II Cycling Tire, Set of 2 Tires
Continental Grand Prix 4000s II Cycling Tire is the ideal combination of comfort, puncture protection and low rolling resistance.
Excellent puncture protection thanks to Vectran puncture protection insert
Perfect all-rounder for all conceivable conditions.
Excellent grip, high mileage and efficient rolling thanks to BlackChili Compound
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 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.
