Wet or dry, soft-packed or rocky, root-infested or grassy—whatever the cyclocross course's terrain, the Challenge Grifo Pro tubular tire excels thanks to its fast-rolling knobs and excellent traction.

  • Features

    • Handmade tires combine many attributes to create comfortable tires with low rolling resistance
    • Tubular construction combines a supple 300 tpi SuperPoly casing with natural rubber tread and seamless latex inner tube
    • This improves grip at lower pressures, offering confident cornering and quick handling
    • Latex is lighter, thinner and more flexible than butyl, increasing comfort, lowering roll resistance and helping to prevent flats
    • Puncture Protection System (PPS) between the tread and casing increases puncture resistance
    • Includes a Presta valve with a removable valve core
    • Ideal for all-terrain use
    • Note: Tire images shown may not reflect size/color/material options available on this page
