Defy the odds as you take the longer route and climb higher mountains with this smooth-riding endurance road bike.
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 tyre 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.
Advanced Com[posite Technology
Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in Giant's 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.
D-Fuse Technology
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride farther, faster.
Overdrive
Giant’s original 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 for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
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 toptube (from the headtube to the seattube) 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.
Tubeless System
Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
RideSense Ready
This frame comes prepared to accept the Giant RideSense sensor and accompanying hardware.
