Defy Advanced Highlights

Ride farther and  faster with an all-new composite frameset featuring endurance geometry and built-in compliance. Handcrafted with Advanced-grade composite material, it’s engineered with tube shapes that are optimized to absorb road shocks and vibrations. And the frame is still stiff in all the ways that matter—for pedaling efficiency as well as steering and cornering  precision. It’s made with a specific carbon layup to give it just the  right feel. And for added control, it features integrated disc brakes  with flat mounts and 12mm thru-axles. The D-Fuse SL composite seatpost  and Contact SL D-Fuse aluminum handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road. The oversized and tapered OverDrive full-composite steerer tube aids cornering precision, while the PowerCore bottom bracket (dropped 5mm from the previous generation Defy to compensate for larger tires) delivers precise handling and class-leading pedaling efficiency.

Advanced Composite Technology

Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

Compliance Tuned Technology

Specific composite layup and tube shaping, including ultra-thin and flattened seatstays, a low seatstay/seattube junction, and thin, slightly curved fork legs combine for a balanced, compliant ride quality and reduced rider fatigue.

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.

Tubeless System

Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s tubeless System makes it easier than ever to experience all these benefits.
