Giant Defy Advanced SL 1 2025

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 SL-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

A 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.

• Weight
  The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
