Technical Details 

BlackChili : It’s all about how you mix it
With our unique tread compound, which is produced only in Germany, we have revolutionised the sport of cycling.
With the legendary BlackChili Compound we have answered the eternal question of the best balance of grip and rolling resistance for cycling.
Regular test wins confirm the measureable and noticeable advantages for the cyclist, established in the laboratory and on the road.
The latest polymers as well as specially developed carbon black particles and filler materials guarantee unique performance

Vectran : 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.
