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 youâ€™re climbing, accelerating and cornering. Itâ€™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 tires 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.
