Giant 2025 Defy Advanced SL 0 Road Bike

Description

Go Long. Go Fast.

Superlight and silky smooth, the flagship of the Defy range, the 2025 Giant Defy Advanced SL 0 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.

With greater lateral stiffness and a superlight frame weight of 785g, this is the most efficient Defy ever. The composite frame layup targets smooth-riding performance for long, hard rides. The new D-Fuse SLR seatpost is now lighter and engineered with 40 percent added compliance. The Contact SLR D-Fuse handlebar, also new, features similar D-shaped tubing as the seatpost to absorb shocks and vibrations, plus an 8-degree flare for improved ergonomics and control. Component highlights include the new Contact SLR AeroLight stem with integrated cable routing. A CADEX 36 WheelSystem with superlight hookless carbon rims delivers snappy yet stable handling and superior tubeless tire performance.

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 minimizes 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 optimized for high-volume tubeless tires (up to 38mm), providing predictable handling and stability from asphalt to cobbles.
