What Our Gearhead(R) Experts Are Saying: "I mounted the Scorpion Race XC M to prep for a marathon course with mixed terrain, and it handled everything with ease. It's fast-rolling, grippy when it counts, and the ProWALL casing gives you that bit of extra security without slowing things down."Pushing the limits of modern cross-country riding takes a tire that can roll fast, grip confidently, and resist flats when the course turns unforgiving. That's why we race and train on the Pirelli Scorpion Race XC M. Born from race tech and built with high-speed XC versatility in mind, this tire thrives on everything from smooth hardpack to muddy, root-laced singletrack. Its Race Compound, developed and produced in Italy, offers chemical grip that keeps us cornering with control in wet and dry conditions alike. A lower-profile tread with a compact center channel keeps rolling resistance low, while the medium-spaced knobs handle acceleration and braking on mixed surfaces. Backing it all up, the reinforced ProWALL casing offers sidewall protection and improved stability at lower pressures, ideal for rough sections and hard pushes through techy climbs.
