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.

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.

×

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.

OVERDRIVE AERO

Found inside the head tube of the all-new Propel range, 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 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.
