The Grand Prix 4000S II is the ultimate race tyre. Featuring the Vectran Breaker for unsurpassed puncture protection and the BlackChili compound for lower rolling resistance and increased grip. This pair of tyres equips you with speed and traction, combined with the LifeLine inner tubes, which are made of high-quality butyl rubber and air leakage tested to ensure excellent reliability.
Vectran is a synthetically manufactured high-tech fibre that is sourced from natural resources. It has comparable properties to spider silk by having enormous tear resistance at a very low weight - exactly the right properties to act as a puncture protection insert for a Continental premium bike tyre. The Vectran Breaker is lighter, more flexible, protects more effectively against cuts than the comparable nylon breaker and does not negatively affect rolling resistance in any way.
Continental have refined newly developed synthetic rubbers with natural rubber with the proven high-performance tread compound. These rubbers are mixed with special nanometric carbon soot particles, which are optimized specifically depending on the shape and surface properties the intended tyre profile requires. Tyres with BlackChili Compound reach an exceptional level of performance, grip, service life and traction that is fine-tuned to the exact intended cycling purpose of the tyre itself.
