Defy Advanced Pro

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 is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

Steerer tube and legs are constructed entirely from Giant’s Advanced SL-grade composite for light weight and precision handling.

The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easier to service system of internally routed brake and derailleur cables.

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.

Lightweight carbon handlebar with D-shaped tubing combines road-smoothing comfort (40% more compliant than the previous generation) with greater pulling (upward) stiffness for better efficiency while sprinting and climbing.

Composite integrated stem with internal cable routing improves aero performance and aesthetics with wind tunnel-inspired design.

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.

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

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

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.
