Giant Defy Advanced 1 (2025) - Frost Silver
Product Code: 9031011123WITH EFFORTLESS EFFICIENCY AND QUIET COMPLIANCE, THIS LIGHTWEIGHT ENDURANCE ROAD MACHINE HELPS YOU RIDE STRONGER AND LONGER. THE COMPOSITE FRAME AND PURPOSE-BUILT COMPONENTS SMOOTH OUT ROUGH ROADS AND MINIMISE FATIGUE.
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, alloy rims are optimised for high-volume tubeless tyres (up to 38mm), providing predictable handling and stability from asphalt to cobbles.
