Continental Grand Prix 4000S II Tire - 700C

Black Chili Compound: A new relationship between grip and rolling resistance. This unique tread rubber mixture which is only produced in Continental's German factory has revolutionized bicycle tires. BlackChili Compound improves rolling resistance by 26 % and provides 30 % more grip than activated silica compounds. Premium tires with BlackChili Compound also impress with higher mileage and unlike many multi-compounds, provide a constant ride from the first to the last mile.

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 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.
