Defy Advanced-Ui2

The Giant Defy Advanced-Ui2 in Satin Tempest Purple represents a high-efficiency carbon endurance road bike built for smoothing out rough asphalt, scaling long mountain passes, and tackling multi-hour sportive rides. Finished in a deep "Satin Tempest Purple" coat, the chassis is crafted from Giant's Advanced-Grade Composite carbon using Compact Road geometry. It pairs an ultra-light frameset with integrated D-Fuse handlebars and D-Fuse carbon seatpost that work in tandem to absorb high-frequency road vibrations and lower rider fatigue.
The build is centered around a full Shimano Ultegra Di2 2x12 electronic drivetrain, delivering fast, precise gear selection across a 50/34T crankset and a wide 11-34T cassette. Rolling on 40mm deep Giant SLR 2 40 Carbon Disc wheels wrapped in supple 700x32c Giant Gavia Fondo 0 tubeless tires (with frame clearance accommodating up to 40mm rubber), stopping performance is handled by Shimano Ultegra hydraulic disc brakes with RT-CL700 rotors.
