This aero rocketship is built for speed when it matters most. It’s lighter than the previous generation and engineered to slice through wind. The result? Race-winning efficiency that puts you ahead of the pack.
Key Performance Factors
Integrated aerodynamics
Easier adjustability
Race-winning efficiency
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.
