Addix makes all the legendary Evo series mountain bike tires even better. With four compounds - Speed, SpeedGrip, Soft, Ultra Soft - Schwalbe can meet all expectations. The names define the range of application and refer to the characteristics of the compound. All laboratory and field tests prove that the properties of Addix compounds are better than any compounds before - in all disciplines: XC, AM and Trail, Enduro and Downhill. Tires with Addix compounds can be easily recognized by the logo on the side of the tire and the colored stripe on the tread.
