Sport/Performance

Handcrafted with Advanced-grade composite material, the Defy Advanced is made with a specific carbon layup to give it an efficient, high-performance ride quality that helps you push new limits of endurance. The D-Fuse seatpost and handlebar system also help reduce road vibrations, adding to its smooth, compliant feel on the road. A tubeless Giant WheelSystem and tires boost speed and efficiency with a reduced risk of flats. And for added control, it features integrated disc brakes with flat-mount disc brake tabs and 12mm thru-axles.

Smooth, fast, and fun. This versatile aluminum road bike has been revamped to give it a well-rounded performance ride quality. It’s the perfect choice to help you push the pace, ride more miles, and expand your road riding experience. Designed for aspiring riders aiming to ride a little faster and go a little farther, Contend offers a smooth, efficient ride quality and a quick, agile feel on the road. The innovative D-Fuse seatpost helps reduce road shocks and vibrations, and there’s enough frame and fork clearance to run wider tires (up to 32mm) to further smooth out the ride. Engineered and built in Giant’s industry-leading aluminum forging facility, it’s a true all-rounder for ambitious road riders. - 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 design reduces road shocks and vibrations, and a Giant WheelSystem lets you run tubeless tires up to 32c for 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 rough roads.

UNLEASH YOUR SPRINT WITH 200 METERS TO GO. CLOSE A GAP, CHASE BACK, LAUNCH A SOLO ATTACK. THIS NEW AERO ROAD MACHINE IS MADE FOR THE MOMENTS THAT COUNT. MORE AERO, MORE ADJUSTABLE, MORE WAYS TO WIN. KEY PERFORMANCE FACTORS Integrated aerodynamics AeroSystem Shaping, a result of CFD analysis and dynamic wind-tunnel testing, optimizes aerodynamic performance at every yaw angle. The truncated ellipse airfoil tube shapes and Contact SLR Aero cockpit produce outstanding overall aero performance. Easier adjustability All-new cable routing through the handlebar and frame makes it quicker and easier to adjust or change cockpit components and fine-tune performance and riding position. Race-winning efficiency Advanced SL-grade composite frameset features Giant’s pro-level composite materials and manufacturing processes. The result is 225 grams of weight savings compared to the previous generation and an even greater stiffness-to-weight advantage. HIGHLIGHTS OF THE PROPEL ADVANCED SL This all-new aero road machine is designed and engineered for one main purpose: speed. With its AeroSystem Shaping technology and race-winning efficiency, it’s the bike of choice for the WorldTour sprinters on Team BikeExchange-Jayco and the world’s fastest triathletes. The tubes feature a truncated ellipse shape for a frame that is both ultra-stiff and superlight. Now 225 grams lighter than the previous generation, it offers a competitive edge when it matters most. AEROSYSTEM SHAPING Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance. ADVANCED SL COMPOSITE Professional-grade raw carbon material is woven in our own composite factory using our most advanced engineering and construction methods including Continuous Fiber Technology, CNT Technology, and Fusion Process. AERO TUBELESS WHEELSYSTEM Engineered with proprietary Dynamic Balanced Lacing technology, this aero WheelSystem and tubeless tires deliver superior efficiency, pinpoint control, and supreme aerodynamics. VECTOR INTEGRATED SEATPOST Designed as a key performance factor in the overall frameset, the integrated seatpost saves up to 45 grams compared to standard composite posts, while improving aerodynamics and adding road-smoothing compliance. 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. FULL COMPOSITE FORK D-shaped steerer tube and legs are constructed entirely from Giant’s Advanced SL-grade composite for the lightest weight and superior handling. POWERCORE A massively oversized bottom bracket area features a fully integrated 86.5mm wide design. Asymmetric chainstays provide additional stiffness on the drive-side and stability on the non-drive-side. NEW CABLE ROUTING Frame and handlebar feature all-new cable porting for sleek, non-cluttered appearance and easier adjustability. 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. AERO HANDLEBAR/STEM Aero handlebar and stem are designed to reduce overall drag while minimizing weight. AERO BOTTLE CAGES Custom-engineered down tube and seat tube-specific water bottle cages help minimize overall aerodynamic drag.
