From climbing steep mountains to tackling rough roads, this bike is designed to help you ride farther and faster, with total confidence.

Lightweight Performance with Simplicity

Advanced Composite Frame: Crafted from Advanced-Grade Composite, this frameset is one of the lightest in its class. It offers a perfect blend of stiffness for high performance and compliance for all-day comfort.

Compact Road Design: Featuring a downward-sloping top tube, it creates smaller front and rear triangles for reduced weight, enhanced stiffness, and a perfect fit for riders of all sizes.

Unmatched Comfort and Compliance

D-Fuse Technology: The handlebar and seatpost work as a system to absorb road shocks and vibrations, reducing fatigue on long rides.

Engineered Compliance: The frame and fork are specifically designed to smooth out rough roads, delivering exceptional ride quality on extended journeys.

Total Control and Stability

Contact D-Fuse Handlebar: Ergonomic shaping with an 8-degree flare enhances control and comfort during long rides.

Carbon Tubeless Wheels: Wide, hookless carbon rims with a 22.4mm inner width and 36mm depth ensure stability and predictable handling, even in crosswinds.

Tubeless System: Designed for high-volume tubeless tyres (up to 38mm), offering fewer flats, lower rolling resistance, and improved traction.

Innovative Technologies for a Superior Ride:

  • Advanced Composite Technology: Built in Giant’s proprietary composite factory, the frame offers a high stiffness-to-weight ratio. Modified Monocoque Construction ensures a durable, precise, and lightweight structure.
  • OverDrive Aero: The D-shaped fork steerer tube, paired with internally routed cables, enhances aerodynamics while simplifying maintenance.
  • Tubeless System: Experience smoother, faster rides with fewer punctures and maximum grip on all surfaces.

This endurance road bike is designed for riders who want to climb higher, ride longer, and enjoy every mile in unmatched comfort and style. Its combination of advanced materials, innovative technology, and precision engineering makes it the perfect choice for tackling challenging routes with ease.

Embrace the freedom of long-distance cycling with the Giant Defy Advanced Pro 2 Road Bike.
