Professional-grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including Continuous Fiber Technology, Carbon Nanotube Technology and Fusion Process.
New
Defy Advanced SL Frameset
Go long. Go fast. Superlight and silky smooth, the flagship frameset of the new Defy range represents the pinnacle of endurance road performance. The frame and fork are both crafted from Giant's pro-level Advanced SL-grade composite, and the new SLR D-Fuse seatpost adds a small amount of flexing action (up to 7mm) for road-smoothing compliance.
Ultralight Carbon Endurance Road Bike Frame
With greater lateral stiffness and a superlight weight of just 785g (size medium, frame only), this is the lightest, most efficient Defy frame ever. It's paired with a new Advanced SL-grade fork that weighs 350g, 15 percent lighter than the previous generation Defy fork. This frameset also includes the new D-Fuse SLR seatpost, which adds 40 percent more road-smoothing compliance compared to the previous generation, and two bottle cages.

Advanced SL Composite
2
OverDrive Aero
The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
3
D-Fuse SLR Seatpost
Proprietary seatpost features a D-shaped composite shaft to better absorb road vibrations without the need for mechanical devices or special inserts. Optimized carbon layup helps increase overall compliance by 40% over previous generation.
4
PowerCore
A massively oversized bottom bracket area features a fully integrated 86mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and increased stability on the non-driveside.
5
Internal Cable Routing
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.
Techs & Features
Advanced SL Composite Technology
Professional Grade raw carbon fiber is woven in our composite factory to produce our lightest, stiffest and highest quality frames. This is the technology used by Giant’s pro racers in almost every cycling discipline.
Compact Road Design
Introduced by Giant with the professional Team ONCE in the 1990s, Compact Road revolutionized 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.
D-Fuse Seatpost
The proprietary “D” shaped composite seatpost damps vibration, resulting in a smooth, compliant ride.
OverDrive Aero
Found inside the head tube of the Defy, Propel and TCR ranges, the D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
