Specifications

With effortless efficiency and quiet compliance, this lightweight endurance road machine helps you ride stronger and longer. The composite frame and purpose-built components smooth out rough roads and minimize fatigue.

Key Performance Factors

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 minimizes 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, alloy rims are optimized for high-volume tubeless tires (up to 38mm), providing predictable handling and stability from asphalt to cobbles.
