GIANT DEFY ADVANCED SL 1 2025 – MOONSTONE

Go long. Go fast. Superlight and silky smooth, the flagship series of the new Defy range is back to reclaim its title as the pinnacle of endurance road. Its the perfect choice for the sportive or gran fondo thats circled on your calendar.

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.

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.

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.
