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.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.Suitable for E-Bikes:- For our E-Bike tyre we fall back on over 100 years' experience with moped and motorcycle tires. All of our city/trekking tires are rated to a standard speed of at least 25 km/h. Those tires marked e50 are also certified for S-Pedelecs. With their high quality structure, puncture protection is high and the rolling resistance is low offering protection from premature wear brought about by the additional driving force.Features:- Versatile competition and trail tire, sure footed in turns and comfortable.- Good grip and available with various technologies.- Smoothly rolling tire that adapts to any terrain with its special tread.- Handmade for You.Specifications:- ETRTO: 55-559- Inch: 26´´- Alternative Dimension: 26 X 2.20- weight (g): 620
