Designed for riders who demand speed, comfort and confidence over long distances, the Giant Defy Advanced Ultegra Di2 combines endurance-focused geometry with cutting-edge carbon technology and wireless electronic shifting. Whether you're tackling all-day sportives, challenging mountain routes or fast-paced weekend rides, the Defy delivers a smooth, efficient and highly capable ride experience.
At the heart of the bike is Giant's Advanced-Grade Composite frame and fork, engineered to balance lightweight performance with exceptional ride quality. The proven endurance geometry offers comfort on long rides without sacrificing responsiveness, while the D-Fuse composite seatpost and Contact SL D-Fuse handlebar help absorb road vibrations, reducing fatigue when the miles start to add up.
Shifting is handled by Shimano's renowned Ultegra Di2 12-speed electronic groupset, delivering lightning-fast, precise gear changes in all conditions. Paired with a compact 50/34 chainset and an 11-34 cassette, the Defy is equally at home spinning up steep climbs as it is powering across rolling terrain.
The bike rolls on Giant's SLR 2 40 Carbon Disc Wheel System, providing aerodynamic efficiency, low weight and excellent responsiveness. Tubeless-ready Giant Gavia Fondo tyres offer superb grip, comfort and puncture protection, while generous clearance for tyres up to 40mm allows riders to tailor the bike for rough roads, endurance events and light gravel adventures.
Finished in a striking Tempest Purple colourway, the Defy Advanced Ultegra Di2 blends premium performance, all-day comfort and modern versatility into one of the most capable endurance road bikes available.
