The frameset, wheels, cockpit and other parts are engineered, developed and tested together to perform as a system. The all-new OverDrive Aero steerer tube technology is combined with a Contact SL AeroLight stem and Contact SL handlebar to incorporate internal cable routing that integrates the top cap, cables and spacers in a more aerodynamic, user-friendly setup.
Featuring a greater stiffness-to-weight ratio than the previous generation, along with new aero tube shaping and a lighter overall weight, this uncompromising race bike delivers explosive acceleration and unyielding pedaling stiffness. The result is race-winning performance in the moments that count.
All tube shapes are engineered and developed using Computational Fluid Dynamics (CFD) modeling and wind-tunnel testing. From the truncated ellipse shape of frameset tubing to a new cockpit design and component integration, it all adds up to a more streamlined profile that improves overall aero performance compared to the previous generation.

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.
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.
Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and easier adjustability.
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.
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.
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.
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 (92-millimeter wide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
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.
