Some roads are smooth, others are rough. This smooth-riding all-rounder handles it all, taking you from the main route to more adventurous options with confidence and control. Key Performance Factors: Balanced road geometry Frame is specifically engineered to produce a balanced, all-rounder feel that blends confident rider positioning with agile cornering and acceleration. Smooth ride quality Innovative D-Fuse seatpost reduces road shocks and vibrations, and a Giant Wheel System lets you run tubeless tires up to 38mm for a smoother ride quality and reduced risk of flats. Total control Seamless disc brake integration, including flat mounts and 12mm front and rear thru-axles, produces more consistent braking power for better control, even in wet weather and on rough roads.

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. 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 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.

Built to go faster. Whether you’re climbing, cornering, or launching an attack, this all-new composite road racer is made for that moment. Lightweight, efficient, and integrated for speed, it’s engineered to give you a competitive edge in every situation. KEY PERFORMANCE FACTORS - SYSTEM OPTIMIZATION The frameset, wheels, cockpit and other parts were engineered, developed and tested together to perform as a system. The all-new Contact AeroLight stem allows for cable routing that integrates the top cap, cables and spacers in a more aerodynamic, user-friendly setup. - WINNING EFFICIENCY Featuring a greater stiffness-to-weight ratio than the previous generation, along with new aero tube shaping and a lighter overall weight, this uncompromising race bike delivers explosive acceleration and unyielding pedaling stiffness. The result is race-winning performance in the moments that count. - INTEGRATED AERODYNAMICS All tube shapes were engineered and developed using Computational Fluid Dynamics (CFD) modeling and wind-tunnel testing. From the truncated ellipse shape of frameset tubing to a new cockpit design and component integration, it all adds up to a more streamlined profile that improves overall aero performance compared to the previous generation. MADE FASTER Newly integrated components including the Contact AeroLight stem create a sleeker, more aero profile. The Variant seatpost adds just enough compliance for a balanced, race-tuned feel on the road, while generous tire clearance (up to 33mm) and compliant wheels keep you rolling with speed on smooth or bumpy roads. TECHS AND 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 molded 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. - 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.

GUNNING FOR THE RACE WIN OR DIGGING DEEP FOR A PR, THIS COMPOSITE ROAD RACING BIKE GIVES YOU THE SPEED, EFFICIENCY AND CONTROL TO PUSH IT TO THE LIMIT, AND THEN A LITTLE BIT MORE. KEY PERFORMANCE FACTORS Class-leading efficiency Combining best-in-class stiffness-to-weight with strategically placed aero-tube shaping, this frameset is engineered for faster climbing, explosive acceleration, and unyielding pedaling stiffness for race-winning performance. Advanced aerodynamics This is where the TCR’s most quantifiable gains can be found compared to previous-generation models. Every tube shape was analyzed, engineered and tested to create an overall structure with significantly lower drag at a wider range of yaw angles. Total control Integrated disc brakes deliver smooth, powerful stopping power and modulation for added control in variable weather and road conditions. Flat mounts and new thru-axles boost stiffness and improve overall handling, while added frame and fork clearance allows for larger diameter tires up to 32mm.
