Black Chili: This unique tread rubber mixture which is only produced in the Continental 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 yield higher wear durability and unlike many multi-compounds, provide a constant performance from the first to the last kilometer.
Vectran: The benchmark in puncture protection. Vectran™ is a synthetically manufactured high-tech fibre from a natural model. Vectran™ has an enormous tear resistance at a very low weight: exactly the right properties to utilize 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 also does not adversely affect the rolling resistance.
