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.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are some benefits of electronic shifting that you don't want to miss.
Electronic shifting systems use powerful servo motors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with surgical precision and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you'll never have to replace a derailleur cable ever again.
