KEY PERFORMANCE FACTORS
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 thru-axles, produces more consistent braking power for better control, even in wet weather and rough roads.

Versatility
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.

ADVANCED COMPOSITE

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.

OVERDRIVE

Giant’s proven oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper) and tapered steerer tube work in conjunction to provide optimal steering stiffness.

D-FUSE TECHNOLOGY

Proprietary D-shaped composite seatpost and handlebar work together to dampen vibrations and absorb road shock, resulting in a smoother, more compliant ride quality.

POWERCORE

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86mm wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

INTERNAL CABLE ROUTING
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.

DISC-BRAKE INTEGRATION
The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.

GIANT WHEELSYSTEM
Engineered with proprietary Dynamic Balanced Lacing technology, this tubeless ready composite WheelSystem delivers superior efficiency, pinpoint control and comfort.
