Technologies
Black Chili Compound
Tyres with BlackChili Compound reach an unprecedented level of performance. Compared to the previous best Activated Silica Compound, BlackChili tyres have 26% less rolling resistance, a 30 % higher friction value (grip) and a 5 % increase in mileage. BlackChili technology never stands still as it is continuously developed. Whether on the road or mountain bike, speed and grip advantages are very noticeable. The complex compound technology is so sensitive that tyres with BlackChili Compound can only be produced exclusively in our German Korbach factory.

Vectran Breaker
For unsurpassed puncture protection. Vectran™ maintains these attributes even in the most adverse weather conditions. Vectran is spun from Vectra liquid crystal polymer, which results in a thread that is thermoplastic and has multifilaments. This semicristalline material is harder then aramid, has five times higher tensile strenght than steel and in addition, is also lighter than comparable nylon thread.
