This versatile road racer combines race-winning stiffness-to-weight with aerodynamic tube shaping and system integration.
From the road-smoothing Variant seatpost to the composite WheelSystem, every piece is optimized as part of the system. The new OverDrive Aero steerer tube technology is combined with a Contact SL AeroLight stem and Contact SL handlebar to incorporate new internal cable routing for easy setup and adjustment, while integrated disc brakes and generous clearance for tires up to 33mm make it adaptable to all road conditions.
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 is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.
Strategically engineered airfoil sections in the frame and fork, developed through CFD and wind-tunnel testing, improve aerodynamic efficiency, reducing wind drag at a wide range of yaw angles compared to traditional teardrop shaped tubes. The frame, handlebar, and stem feature unique cable porting for a sleek, non-cluttered appearance and easier adjustability.
The Advanced SL-grade composite fork features a symmetric design and aero shaping, along with disc-brake integration and increased clearance for tires up to 33mm. The design makes it lighter, stiffer, and more aerodynamic.
Lightweight handlebar and stem feature aero shaping including flat handlebar tops with raised edges to help riders maintain a stable aero position. Internal cable routing further improves aerodynamics while maintaining ease of setup and adjustment.
The D-shaped fork steerer tube and corresponding spacers provide an extremely aerodynamic, easy-to-service system of internally routed brake and derailleur cables.
This proprietary seatpost design offers the perfect balance of light weight, aerodynamic performance, and compliance, along with easy saddle installation and adjustment.
An oversized down tube and top tube provide superior front end lateral and torsional stiffness. The precisely engineered, rectangular shaped down tube yields unprecedented steering precision and pedaling performance.
The oversized bottom bracket area features a fully integrated 86mm wide design. Symmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Engineered with proprietary Dynamic Balanced Lacing and composite spokes, this tubeless ready composite WheelSystem delivers superior efficiency, comfort, and control in a user-friendly system.
The frame and fork are engineered with flat-mount disc-brake technology for powerful, consistent braking performance in all conditions.
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.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant's Tubeless System makes it easier than ever to experience fewer flat tires, greater traction, less rolling resistance, and a smoother, faster ride.
