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 minimize fatigue.

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 minimizes 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 optimized for high-volume tubeless tires (up to 38mm), providing predictable handling and stability from asphalt to cobbles.

Lightweight Carbon Endurance Road Bike

With an all-new composite chassis that combines efficiency with compliance, this endurance road machine will have you logging more miles at a greater average speed. The combination of a D-Fuse seatpost and handlebar, both featuring D-shaped tubing to better absorb shocks and vibrations, helps you stay smooth no matter how rough the road. The new Contact AeroLight stem has cleanly integrated cable routing. And the frameset offers clearance for high-volume tires up to 38mm.

Advanced Composite

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 is assembled and molded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

D-Fuse Seatpost

Proprietary seatpost features a D-shaped composite shaft to absorb road vibrations without the need for mechanical devices or special inserts. Optimized carbon layup helps increase overall compliance.

Contact SL D-Fuse Handlebar

Lightweight carbon handlebar with D-shaped tubing combines road-smoothing comfort with greater pulling (upward) stiffness for better efficiency while sprinting and climbing.

Contact Aerolight Stem

Composite integrated stem with internal cable routing improves aero performance and aesthetics with wind tunnel-inspired design.

PowerCore

A massively oversized bottom bracket area features a fully integrated 86mm wide design. Asymmetric chainstays provide additional stiffness on the driveside and increased stability on the non-driveside.

Internal Cable Routing

Frame/handlebar/stem feature unique cable porting for sleek, non-cluttered appearance and performance.

Disc-Brake Integration

The frame and fork are engineered specifically for flat-mount disc-brakes, including front and rear 12mm thru-axles for reliable braking performance in all weather and road conditions.

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

Controlled Compliance

Giant first introduced its breakthrough D-Fuse technology in 2014 as a seatpost for pro-level cyclocross bikes. It was designed to absorb low-amplitude shocks and high-amplitude vibrations to deliver a smoother ride on variable terrain. The heart of this pioneering concept is its distinctive “D-shaped” tubing with a round front and flattened rear section. Following its success in cyclocross, including multiple world championship titles, D-Fuse technology was expanded to endurance road and gravel bikes—and later to the front half of the bicycle. Together, the handlebar and seatpost add compliance at two key contact points without the unwanted complexity or weight associated with pivots or inserts. There are several D-Fuse handlebar models currently available. Each is lighter than round-shaped handlebar options and up to 40 percent more compliant than previous-generation D-Fuse handlebars.

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 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.
