Oh! Come and see the violence inherent in the system! Help, help, I'm being repressed! We shall say 'Ni' again to you, if you do not appease us. I'm not a witch. I'm not a witch. Camelot!

Engineered compliance
Advanced Composite frame is specifically engineered for endurance road riding, giving you a smooth ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar absorb road shocks and vibrations.

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

Endurance road geometry, added tire clearance (up to 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged mountain passes.

Handcrafted with Advanced-grade composite material, the Defy Advanced is 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.
