Choose the longer route and climb higher mountains with the Giant Defy Advanced 1 endurance road bike.

• Engineered compliance: The Advanced Composite frame is designed for endurance road riding. The D-Fuse seatpost and handlebar absorb road shocks and vibrations, providing a smooth ride quality for reduced fatigue on long rides.
• Total control: Seamless disc brake integration with flat mounts and 12mm front and rear thru-axles offer consistent braking power for better control, especially in wet weather and on rough roads.
• Versatility: Enjoy the endurance road geometry, ample tire clearance (up to 35mm), and disc-brake integration, allowing you to tackle various road conditions from smooth pavement to rugged mountain passes.

Technologies

• Advanced Composite Technology: Giant’s High-Performance Grade carbon material produces a custom frame with high stiffness-to-weight ratio, ensuring a sturdy structure. The assembly of the front triangle is done as one continuous piece through Modified Monocoque Construction.
• D-Fuse Technology: The D-Fuse seatpost and handlebar work as a system to absorb road shocks and vibrations, enabling you to ride longer and faster.
• OverDrive: Giant’s oversized fork steerer tube technology provides precise front-end steering performance. The oversized headset bearings and tapered steerer tube ensure optimal steering stiffness.
• Compact Road Design: Introduced by Giant in the 1990s, this design features a downward-sloping toptube for smaller front and rear triangles. This creates a lighter, stiffer bike and improves the fit for riders of all sizes.
• Tubeless System: Giant’s Tubeless System reduces flat tires, increases traction, lowers rolling resistance, and offers a smoother, faster ride experience.
