Technical details
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
Puncture-defence
With our PolyX Breaker®, we bring our car expertise to the bicycle tire segment: Polyester has been used successfully for years in car tires and been tried and tested many times. The extremely resistant polyester fibre is woven tightly crosswise. In this way, a very high fabric density is reached which not only makes the Breaker more resistant to foreign objects but is also especially resistant to punctures. The rolling resistance is also not negatively affected by the PolyX Breaker®.
