    Smooth, superlight and built for compliance. From gran fondos to epic solo rides, this new, re-engineered Defy Advanced Pro represents the pinnacle of endurance road performance.

    Engineered compliance: Advanced Composite frame is specifically engineered for endurance road riding, delivering a smooth ride quality ensuring less fatigue on long rides. The D-Fuse seatpost and handlebar system work seamlessly with the frame to absorb road shocks and vibrations.

    Total control: Seamless disc brake integration including flat mounts and 12mm front and rear thru-axles produces more consistent braking power for better control, even in wet weather and on rough roads.

    Versatility: Endurance road geometry, added tyre clearance (up to 32c) and disc brake integration allow you to tackle a variety of roads and conditions.

    Advanced Composite Technology

    High-performance grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and moulded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

    Compact Road Design

    Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionised the look and feel of high-performance road bikes forever. A downward sloping top tube (from the head tube to the seat tube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.

    Compliance Tuned Technology

    Specific composite layup and tube shaping, including ultra-thin and flattened seat stays, a low seat stay/seat tube junction and thin, slightly curved fork legs combine for a balanced, compliant ride quality and reduced rider fatigue.


    Named for the shape of the seatpost and handlebar, the lightweight D fuse components work as part of the bike to significantly reduce road vibrations and aid compliance.

    Disc brake integration

    The frame and fork are engineered specifically for disc brakes for reliable braking performance in all weather and road conditions.

    OverDrive 2

    The most advanced steerer tube technology in today’s Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.

    Giant Tubeless System

    Integrated Tubeless WheelSystem and tyres delivers improved efficiency, comfort and control in the most user-friendly and reliable system.
