Giant Defy Advanced SL 0 (2025)
Giant Defy Advanced SL 0 Road Bike (2025)
Go long. Go fast. The Giant Defy Advanced SL 0 is the crown jewel of the revamped Defy lineup—crafted to conquer epic gran fondos and sportive rides with superlight precision and supreme comfort. Designed for endurance without excess, it’s built to help you ride further, faster, and smoother than ever before.
Functional simplicity
This no-nonsense endurance machine strips away gimmicks in favour of purposeful performance. The SL-grade composite frameset is one of the lightest in its class, engineered to provide high responsiveness on climbs and long-haul comfort without compromise.
Engineered compliance
The Advanced SL composite frame and fork are tuned specifically for endurance riding, absorbing road buzz and vibrations to keep fatigue at bay. Integrated D-Fuse components—seatpost, handlebar and more—further enhance ride compliance and efficiency over rough surfaces.
Total control
The Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare, giving you better control on extended efforts. The wide, hookless carbon rims are optimised for high-volume tubeless tyres (up to 38mm) with a 22.4mm internal width, while a 36mm rim depth balances aerodynamics and crosswind stability.
