    Here’s to long rides. Climb higher, skip the shortcuts. This smooth endurance road bike helps you do more of what you love.

    Functional simplicity

    Free of cumbersome gimmickry, the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort, it offers a “less is more” experience for modern endurance road riding.

    Engineered compliance

    Advanced-grade composite frame and fork are specifically engineered for endurance road riding, delivering a smooth and efficient ride quality that minimises fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations.

    Total control

    New Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide, hookless carbon rims are optimised for high-volume tubeless tires (up to 38mm).
