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 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.
Advanced Composite Frame
OverDrive 2
Giant’s most advanced steerer tube technology offers unprecedented steering precision. Oversized headset bearings (1 1/2” lower, 1 1/4" upper) and a tapered steerer tube produce superior front-end stiffness.
D-Fuse Technology
Proprietary D-shaped composite seatpost and handlebar work together to dampen vibrations and absorb road shock, resulting in a smoother, more compliant ride quality.
PowerCore
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
Giant Composite WheelSystem
Engineered with proprietary Dynamic Balanced Lacing technology, Giant’s all-new SLR Disc Composite WheelSystem delivers superior efficiency, pinpoint control and comfort. The wheels are integrated with Giant Gavia Fondo 32c tubeless tires for added rolling efficiency and a reduced risk of flats.
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.
Internal Seatpost Clamp
Lightweight, all-internal seatpost locking mechanism provides clean, confident clamping power where it is needed most.
