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.

Where Performance Takes Off A true performance road bike with race-winning DNA – delivering champagne experience for lemonade money. Where it thrives The open road, In competition What it's built for Speed, Handling, Durability Highlights - Lightweight SmartForm C2 Alloy Frame w/ full carbon fork - Shimano Claris 8-speed shifting / FSA Tempo crank - Promax RC-452 dual pivot brakes Exceptional Aluminum Performance Everything we know about aluminum road bikes in one space – refined tube profiles, precision butting, and double-pass welds create frames that are lighter and ride better than our competitors’ high-ticket alloy offerings. Elite Race Geometry With geometry influenced directly from our award-winning CAAD13 bike, the CAAD Optimo offers true race handling and optimal body position at all times. Ride Smoother with SAVE Along with Optimo’s new dropped seatstay profile, finely engineered flex zones in the rear of the frame absorb road chatter for better comfort and control. Full Carbon Fork Premium carbon fork features full carbon fiber construction and a tapered steerer, for ultra low weight, and maximum steering precision. Versatility Built In Subtle rack and fender mounts expand CAAD Optimo's versatility for commuting/wet weather training. Smoother Than Ever CAAD bikes have always been known for their surprisingly smooth ride. CAAD Optimo features a newly designed SAVE rear triangle to absorb road chatter for better comfort and control.

Road Reimagined Go long, go short, go fast. This is WorldTour performance for real world rides. Highlights - Lightweight, smoothly compliant, sleekly aero Synapse carbon frameset with StashPort downtube storage - Smooth, consistent, reliable 2x12-speed shifting from Shimano's trusted 105 mechanical drivetrain - DT Swiss 470 rims with Vittoria Rubino Pro IV 32c tires - grip, durability, and speed - Cannondale C1 Aero 27 Carbon seatpost - speed meets comfort

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.
