With effortless efficiency and quiet compliance this lightweight endurance road machine helps you ride stronger and longer. The composite frame and purpose-built components smooth out rough roads and minimise fatigue. Key Performance Factors Functional simplicity Free of cumbersome gimmickry the frameset is one of the lightest in its category. With a perfect balance of high-performance reactivity and all-day comfort it offers a “less is more” experience for modern endurance road riding. Engineered compliance Advanced-grade composite frame and fork are specifically engineered for endurance road riding delivering a smooth and efficient ride quality that minimises fatigue on long rides. The new D-Fuse components work together to further absorb road shocks and vibrations. Total control New Contact D-Fuse handlebar features ergonomic shaping and an 8-degree flare for comfort and control on all-day rides. Wide alloy rims are optimised for high-volume tubeless tyres up to 38mm providing predictable handling and stability from asphalt to cobbles. 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. D-Fuse Technology The D-Fuse seatpost and handlebar were designed to function as a system absorbing road shocks and vibrations so you can ride farther faster. 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. Compact Road Design 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.

Many brands strive to list the lowest possible weight but in reality weight can vary based on size finish hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
