  • The multiple world champion tire in Cyclo Cross: specially developed profile. The right choice for professionals and frequent riders. Incredible grip with very low rolling resistance.

    Range of use:

    All-round cyclo-cross tire for wet, dry, soft, rocky or root-covered trails.

    Features:

    Pro Handmade Clincher with Superpoly carcass.

    Handmade tires combine a variety of outstanding features to provide the highest comfort and lowest rolling resistance. Carefully selected materials are used depending on use performance requirements in the various tire levels. Soft, supple carcasses quickly adapt to the shape of the ground when rolling and cornering. This increases ground contact and grip and improves shock absorption on poor road surfaces. Soft, natural rubber treads are combined with lightweight, flexible puncture protection.
    Polyester is the least expensive of all handmade carcasses. It is a synthetic fabric that is very strong and impervious to water, offering much more flexibility and durability than comparable nylon materials. Challenge uses high quality polyester or SuperPoly (higher TPI polyester) to produce cost effective pro-level tires.

    Handmade Natural Rubber - Hardness Smart

    Challenge's handcrafted natural rubber treads are compounded to provide the perfect level of durability without sacrificing performance, comfort and control. Challenge tires wear out 10-20% faster than the competition, but score with significantly improved performance and noticeably better feel throughout their life. Depending on the requirements, the tires are equipped with different soft rubber compounds.
    The Smart hardness grade is the variant of Challenge's natural rubber compounds optimized for long service life.

    Puncture Protection System (PPS)

    The PPS (Puncture Protection System) puncture protection system consists of one or more layers of fabric between the tread and the tire carcass. PPS significantly increases the tire's resistance to punctures and thus offers maximum reliability.
