Smooth, superlight and built for compliance. From gran fondos to epic solo rides, this new, reengineered Defy Advanced Pro represents the pinnacle of endurance road performance.

This all-new high-performance frameset is handcrafted with Giant’s Advanced composite and specifically engineered for endurance road riding. With the perfect blend of stiffness and compliance, it delivers a smooth, fast ride quality for your longest, hardest rides. Its innovative technologies include a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar, specially shaped cockpit components that work as a system to add compliance and reduce road shocks and vibrations. The frame is also integrated for disc brakes, with flat mounts and 12mm front and rear thru-axles, plus clearance for high-volume tyres up to 32c. The oversized and tapered OverDrive 2 steerer tube boosts cornering precision, while the MegaDrive downtube and PowerCore bottom bracket deliver precise handling and class-leading pedalling efficiency.

Key Performance Factors

Engineered compliance

Advanced Composite frame is specifically engineered for endurance road riding, delivering a smoother ride quality and less fatigue on long rides. The D-Fuse seatpost and handlebar system works seamlessly with the frame to absorb road shocks and vibrations.

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.

Versatility

Endurance road geometry, added tyre clearance (up to 32c) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.
