The Giant Defy Advanced 1 Road Bike is a high-performance endurance road bike designed to help you ride further, faster, and with greater comfort. Its lightweight frame, engineered compliance, and precision handling make it ideal for conquering long rides on varied terrains with ease.

Effortless Performance

Lightweight Frameset: Built from Advanced-Grade Composite, this frame is among the lightest in its class. It strikes the perfect balance of reactivity and endurance comfort, ensuring exceptional efficiency on long rides.

Compact Road Design: A signature Giant innovation, the downward-sloping top tube enhances stiffness, reduces weight, and ensures a precise fit for riders of all sizes.

Engineered for Comfort

Advanced Compliance: The frame and fork are purpose-built for endurance, absorbing road shocks to minimise fatigue over extended distances.

D-Fuse Technology: The seatpost and handlebar work as a system to reduce vibrations, ensuring a smoother ride even on rough roads.

Total Control for Every Ride

Contact D-Fuse Handlebar: Features an ergonomic design and 8-degree flare for superior control and all-day comfort.

Tubeless Ready System: Wide alloy rims are optimised for high-volume tubeless tyres (up to 38mm), offering improved traction, fewer flats, and lower rolling resistance on diverse surfaces.

Advanced Technologies That Define the Ride:

  • Advanced Composite Technology: Constructed from Giant’s proprietary high-performance carbon material, the frame boasts a superior stiffness-to-weight ratio. Its Modified Monocoque Construction ensures durability and efficiency.
  • OverDrive Aero: Internally routed cables and a D-shaped fork steerer improve aerodynamics and make servicing easier, enhancing both performance and functionality.
  • Tubeless System: Experience smoother, faster rides with fewer punctures and enhanced grip, thanks to Giant’s reliable tubeless integration.
