Schwalbe Racing Ralph Evolution Folding MTB Tire - SuperGround A fast and versatile XC profile paired with Addix Speed Compound makes Racing Ralph an XC weapon and an ingenious addition to Racing Ray. Developed especially for the rear wheel, the tire impresses with many grip edges in the middle area for great traction and excellent acceleration. Thanks to its fast and versatile XC profile, it also has excellent rolling properties. Laterally arranged tread blocks that protrude far into the running surface offer the best possible cornering grip. Specially designed spaces also increase traction on roots and rocky ground and strengthen the self-cleaning properties of the tire. Thanks to the ADDIX compound, the overall concept of this race tire is rounded off as best as possible. In addition, the new tire has a bead-to-bead fabric for improved protection against cuts. EvolutionLine The Evolution tires are the top models in the Schwalbe . Extremely fast, very light with good mileage make these tires the first choice for all ambitious athletes! Schwalbe only uses the best available materials for its top products in order to meet all the requirements placed on a tire! ADDIX The new compound for the tires of the Performance Line, more grip, more speed, more mileage. Schwalbe succeeded in doing this with a new mixing process in which the components for the manufacture of the rubber compound can be added more precisely. ADDIX Speed, red identification: The new compound for the XC Race specialists rolls quickly and has a significantly longer service life. TLE - Tubeless Easy A new monofilament side fabric brings three advantages over the previous standard: Even better cut resistance, increased puncture resistance and, above all, it enables extremely easy tubeless conversion. The use of sealing fluid is required, but assembly is otherwise just as easy as with real tubeless tires. Long conversion processes with intensive shaking and frequent pumping are no longer possible with Tubeless Easy. SnakeSkin The SnakeSkin side fabric guarantees additional cut-proof side walls and thus increases puncture resistance. Super ground The proven SnakeSkin construction has been further improved - a light and flexible fabric layer makes the tire cut securely, both on the tire sidewalls and under the tread. Low weight with good puncture protection. Wide intended use - from cross-country to all-mountain.
