Sport/Performance

SMOOTH, FAST AND FUN. THIS VERSATILE ALUMINUM ROAD BIKE HELPS YOU PUSH THE PACE, RIDE MORE MILES, AND EXPAND YOUR ROAD RIDING EXPERIENCE. 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 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 rough roads.

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 WheelSystem 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.

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.

MAXIMIZE YOUR WATTS DURING SPRINTS, BREAKAWAYS AND SOLO ATTACKS. THIS AERO ROAD MACHINE IS RE-ENGINEERED TO GIVE YOU A REAL ADVANTAGE AGAINST THE WIND. BECAUSE SMALL GAINS LEAD TO BIG WINS. 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 all-new Contact SL Aero cockpit produce superior aero performance. Race-winning efficiency Advanced-grade composite frame and hybrid alloy/composite fork deliver optimal stiffness and weight savings. The result is an even greater stiffness-to-weight advantage. 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. HIGHLIGHTS OF THE PROPEL ADVANCED AERO BIKE Engineered with AeroSystem Shaping technology and Advanced-grade composite material, the all-new Propel Advanced combines proven aero performance and one of the lightest framesets in its category. New cable routing through the stem and head tube makes it quick and easy to adjust and dial in rider positioning. The lightweight, easily adjustable Vector composite seatpost further minimizes drag. AEROSYSTEM SHAPING Through CFD (Computational Fluid Dynamics) and wind-tunnel data, engineers optimize each tube shape to deliver superior aerodynamic performance. ADVANCED COMPOSITE High-performance grade raw carbon material is used to produce this custom material in our own composite factory with a high stiffness-to-weight ratio. AERO TUBELESS WHEELSYSTEM Engineered with proprietary Dynamic Balanced Lacing technology, this composite aero WheelSystem and tubeless tires deliver superior efficiency, pinpoint control, and superior aerodynamics. 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 fork legs are constructed entirely from Giant’s Advanced-grade composite for light 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. VECTOR SEATPOST This full-composite, lightweight and aerodynamic seatpost is engineered specifically for performance road riding. NEW CABLE ROUTING Frame and handlebar feature unique cable porting for a 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.
