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, hookless carbon rims (22.4mm inner width) are optimised for high-volume tubeless tyres (up to 38mm), and a 36mm rim depth offers stable, predictable handling in crosswinds.

TECHS & FEATURES

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 moulded 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 further, faster.absorbing road shocks and vibrations so you can ride further, faster.

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.

TUBELESS SYSTEM

Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.

OVERDRIVE AERO
