About Giant Defy Advanced Pro 1 2021
Go longer, go faster and smooth out rough roads with a frameset and integrated components that are engineered for compliance. From gran fondos to epic solo rides, this lightweight composite bike is everything you need for your most challenging days.

With the perfect blend of stiffness and compliance, Defy Advanced Pro delivers a smooth, fast ride quality even on rough roads. Its innovative technologies include a D-Fuse composite seatpost and Contact SLR D-Fuse composite handlebar. These integrated cockpit components work as a system to add compliance and reduce road shocks and vibrations. The Advanced-grade composite frame is also integrated for disc brakes, with flat-mount disc brake tabs and 12mm front and rear thru-axles, plus clearance for high-volume tyres up to 35mm. 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 35mm) and disc-brake integration allow you to tackle a variety of roads and conditions, from smooth pavement to rugged backroads and mountain passes.
