Maximize your watts during sprints breakaways and solo attacks. This aero road machine is built to give you a real advantage against the wind. Because small gains lead to big wins. Key Performance Factors Integrated aerodynamics AeroSystem Shaping a result of CFD analysis and dynamic wind-tunnel testing optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and all-new Contact SL Aero cockpit produce superior aero performance. Easier adjustability All-new cable routing through the stem and head tube makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position. Race-winning efficiency Advanced-grade composite frame and fork deliver optimal stiffness and weight savings. The result is an even greater stiffness-to-weight advantage. Advanced Composite Technology 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. AeroSystem Shaping Technology Through CFD Computational Fluid Dynamics and wind-tunnel data engineers optimize each tube shape to deliver superior aerodynamic performance. 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. Tubeless System Fewer flat tires. Greater traction. Less rolling resistance and a smoother faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
