The maximum inflation pressure for hookless and hooked applications as well as the maximum inner rim width can be found on the tire packaging and may differ between hooked and hookless applications. You can find more information here or in the mounting guidelines.


Technical Highlights

Light, fast, safe

Developed together with professional mountain bikers, the RaceSport carcass unites light-weight construction with noticeably improved puncture protection for the perfect competition choice. Light: contains a particularly fine, flexible nylon fabric with an elaborately produced protective rubber coating. Fast and reliable: World Cup quality, low rolling resistance and puncture protection. Combined with our legendary BlackChili Compound, the right combination for XC and Marathon racing.

It’s all about how you mix it

Black Chili

The rolling properties of the rubber compound of a tire are primarily determined by three interacting factors – stiction [grip], rolling resistance and mileage [longevity] . The dilemma: If you improve any of these factors it can have a detrimental effect on at least one of the others. A tire with maximum grip wears quicker and rolls more slowly. If you then make a tire roll faster and more durable, grip, in turn, is reduced.

With our Black Chili compound, a tread compound which is always based on the latest knowledge of polymers and raw material research, we have supplied the cycling industry with an enduring solution. Depending on the application of a tire, we adjust the compound formulation for the specific discipline – for road or mountain biking, time trialling or downhill racing.

How does that work? For Black Chili we refine special synthetic rubbers with proven natural rubber to high-performance tread mixtures. To these mixtures we then add soot particles, which in turn are optimised in shape and surface properties.
