The Giant Defy Advanced 3 Road Bike is your ultimate companion for endurance rides, delivering effortless efficiency and unmatched comfort. Designed to help you ride farther and stronger, this lightweight endurance road bike features a high-performance composite frame that smooths out rough roads and reduces fatigue, so you can enjoy longer, more comfortable rides.

Functional Simplicity

The Giant Defy Advanced 3’s lightweight frameset is free from unnecessary complexity, offering a perfect balance of responsiveness and all-day comfort. It provides a streamlined, modern experience for endurance road cyclists who value efficiency and simplicity.

Engineered Compliance

The Advanced-grade composite frame and fork are tailored for endurance, absorbing road vibrations to deliver a smooth and efficient ride. Paired with the D-Fuse seatpost and handlebar, this system minimises fatigue by reducing shocks, letting you stay comfortable on long journeys.

Total Control

The newly designed Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for enhanced comfort and control during extended rides. Wide hookless carbon rims with a 22.4mm inner width are optimised for tubeless tyres (up to 38mm), offering stability and dependable handling in crosswinds.

Innovative Technology

  • Advanced Composite Technology: Crafted with Giant’s high-performance-grade carbon, the frame is lightweight yet stiff, built using a proprietary Modified Monocoque Construction process for maximum efficiency.
  • D-Fuse Technology: The D-shaped seatpost and handlebar absorb road shocks and vibrations, ensuring a smoother, faster ride over varied terrain.
  • Compact Road Design: A sloping toptube creates smaller triangles for a lighter, stiffer bike that fits riders of all sizes perfectly.
  • Tubeless System: Enjoy fewer flats, better traction, reduced rolling resistance, and a faster, smoother ride with Giant’s integrated tubeless technology.
  • OverDrive Aero: Internally routed cables and a D-shaped steerer tube deliver improved aerodynamics and a clean look while ensuring easy maintenance.

Versatile and Comfortable

Designed for endurance, the Defy Advanced 3 features generous tyre clearance for up to 38mm tyres, making it adaptable to varied road conditions. From the smoothest roads to rougher terrain, this endurance machine delivers efficiency and compliance to keep you logging more miles with confidence.
