Giant Defy Advanced SL 1 2026 Road Bike
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. It’s the perfect choice for the sportive or gran fondo that’s circled on your calendar.
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 SL-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
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 optimized for high-volume tubeless tires (up to 38mm), and a 40mm rim depth offers stable, predictable handling in crosswinds.
