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

Functional simplicity

Free of cumbersome gimmickry, our carbon-fibre 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

Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides.

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

KEY FEATURES

  • Advanced-grade carbon endurance frame & fork – Lightweight, smooth and fatigue-reducing for long-distance riding.
  • Shimano 105 Di2 12-speed – Precise electronic shifting with 50/34T x 11-36 gearing for versatile climbing and speed.
  • D-Fuse cockpit & seatpost – Engineered compliance to absorb road vibration without sacrificing efficiency.
  • 30mm alloy tubeless wheels – Stable, predictable handling with 32c tyres fitted and up to 38mm clearance.
