Key Performance Factors

• Functional Simplicity: Free of cumbersome gimmickry, the frameset is one of the lightest in its category, offering high-performance reactivity and all-day comfort.
• Engineered Compliance: Advanced SL-grade composite frame and fork deliver a smooth ride quality that minimizes fatigue. D-Fuse components work together to absorb road shocks.
• Total Control: New Contact D-Fuse handlebar with an 8-degree flare and wide CADEX hookless carbon rims provide stable, predictable handling in all conditions.

Advanced Technologies

• Advanced SL Composite: Professional Grade raw carbon fiber woven in Giant's own factory for the lightest and stiffest frames.
• D-Fuse Technology: The seatpost and handlebar function as a system to absorb vibrations, allowing you to ride farther and faster.
• OverDrive Aero: D-shaped fork steerer tube and matching spacers provide an aerodynamic, easier-to-service system for internal cable routing.
• PowerCore: Massively oversized bottom-bracket area for maximum pedaling stiffness and stability.
• Tubeless System: Greater traction and less rolling resistance for a smoother, faster ride with fewer flat tires.
