Giant Defy Advanced Pro 2

Giant Defy Advanced Pro 2


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 tires 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 pedaling efficiency.
