Ride Further, Climb Higher, and Push Your Endurance Limits
The Giant Defy Advanced Pro 1 is a premium endurance road bike designed for long-distance rides and challenging climbs. Combining a lightweight composite frame, engineered compliance, and cutting-edge components, this bike delivers unmatched comfort, control, and efficiency to help you conquer every road and ride stronger, longer.
Lightweight, Simplified Performance
Built with an Advanced-grade composite frameset, the Defy Advanced Pro 1 is one of the lightest in its category. The minimalist design prioritises a high stiffness-to-weight ratio for a responsive yet comfortable ride. The result is a “less is more” experience tailored for modern endurance cycling.
Engineered for Smooth Compliance
The Advanced-grade composite frame and fork are purpose-built to absorb road shocks and vibrations, reducing rider fatigue on long rides. Giant’s innovative D-Fuse technology in the seatpost and handlebar further enhances compliance, delivering a buttery-smooth ride quality for all-day comfort.
Total Control and Stability
The new Contact D-Fuse handlebar features an ergonomic design with an 8-degree flare for improved comfort and precise control. The bike is equipped with hookless carbon rims (22.4mm inner width) optimized for high-volume tubeless tyres (up to 38mm). A 36mm rim depth enhances stability and predictable handling, even in challenging crosswind conditions.
Advanced Composite Technology
Using Giant’s High-Performance Grade raw carbon material, the frameset is manufactured with a proprietary Modified Monocoque Construction process. This results in an ultra-light, stiff, and strong frame that enhances both efficiency and durability.
Compact Road Design
Pioneered by Giant, the Compact Road Design revolutionised road bike geometry. The sloping top tube creates smaller front and rear triangles, resulting in a lighter, stiffer, and more agile frame. It also ensures a perfect fit for riders of all sizes.
D-Fuse Technology
The D-Fuse seatpost and handlebar system work together to absorb shocks and vibrations from rough roads, allowing you to ride further, faster, and in greater comfort.
OverDrive Aero System
The innovative D-shaped fork steerer tube and spacers provide an aerodynamic advantage and allow for clean, internal cable routing. This design also simplifies maintenance while enhancing speed and efficiency.
Giant Tubeless System
Enjoy the benefits of tubeless technology, including:
- Fewer flat tyres
- Improved traction and control
- Lower rolling resistance
- Smoother, faster rides
Giant’s Tubeless System is easy to set up and delivers unmatched performance on a variety of road surfaces.
Power Halo for Training Precision
The all-new Power Halo makes power-based training accessible to all riders. Simple to set up and easy to use, it provides clear, accurate metrics to help you track performance and train like a pro.
