Highlight
CHOOSE THE LONGER ROUTE. CLIMB HIGHER MOUNTAINS. THIS SMOOTH-RIDING ENDURANCE ROAD BIKE IS PURPOSE-BUILT TO HELP YOU TACKLE LONG-DISTANCE ROAD RIDES ON ALL TYPES OF ROADS.
Handcrafted with Advanced-grade composite material, the Defy Advanced is engineered with tube shapes that are optimized to absorb road shocks and vibrations. Even with its smooth ride quality, it still delivers a lightweight, stiff and lively feel when you’re climbing, accelerating and cornering. It’s made with a specific carbon layup to give it an efficient, high-performance ride quality that helps you push new limits of endurance. The D-Fuse seatpost and handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road. A tubeless Giant WheelSystem and tyres boost speed and efficiency with a reduced risk of flats. And for added control, it features integrated disc brakes with flat-mount disc brake tabs and 12mm thru-axles.
KEY PERFORMANCE FACTORS
Engineered compliance
Advanced Composite frame is specifically engineered for endurance road riding, delivering a smoother ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar system works 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 rough roads.
Versatility
Endurance road geometry, added tyre clearance (up to 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes.
