Product Code: 9031014103HERE’S TO LONG RIDES. CLIMB HIGHER MOUNTAINS, SKIP THE SHORTCUTS. THIS BUTTERY SMOOTH ENDURANCE ROAD BIKE HELPS YOU DO MORE OF WHAT YOU LOVE.
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 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 (22.4mm inner width) are optimised for high-volume tubeless tyres (up to 38mm), and a 36mm rim depth offers stable, predictable handling in crosswinds.
