    Carbon frame and fork

    Stiff, fast, agile, and extraordinarily light carbon frame.

    Endurance race inspired geometry

    Thin seat stays increase compliancy over the bumps, increasing comfort without sacrificing stiffness and speed.

    Internal cable routing

    Full internal routing means tidy cables, clean lines, and reduced potential for cable snags.

    Tapered headtube

    Tapered steerer and headtube gives more precise cornering and increases feedback when riding.

    Tyre clearance

    Clearance for up to 32 mm tyres (Reef forks) or 28 mm tyres (Nemo forks)

    Forgiving angles

    A longer wheel base promotes stability and comfort on the downhills.
