The Giant Defy Advanced-Ui2 is built around the idea that endurance performance doesn't need unnecessary complexity. Its Advanced-Grade Composite frame and fork deliver an excellent balance of low weight, responsive handling and all-day comfort, making it a strong choice for sportive riders, long-distance cyclists and anyone looking to explore beyond perfectly smooth tarmac.
Engineered specifically for endurance road riding, the frameset is designed to reduce fatigue without compromising efficiency. The lightweight carbon construction responds quickly when climbing or accelerating, while carefully tuned compliance helps smooth out rough roads, broken surfaces and long hours in the saddle.
A major contributor to the Defy's comfort is Giant's D-Fuse technology. The Contact SL D-Fuse handlebar and Giant D-Fuse composite seatpost are designed to absorb road vibrations before they reach the rider. The handlebar also features ergonomic shaping and an 8-degree flare, providing a comfortable hand position and confident control on everything from fast descents to rough back roads.
Shifting duties are handled by Shimano's Ultegra Di2 12-speed electronic groupset. Renowned for its fast, precise gear changes, it delivers reliable performance whether you're climbing steep gradients, riding in a group or covering big miles. The combination of a compact 50/34T Ultegra chainset and an 11-34T cassette provides a versatile gear range suitable for varied terrain.
Stopping power comes from Shimano Ultegra hydraulic disc brakes with 160mm rotors front and rear. They offer excellent modulation and dependable braking performance in all weather conditions, helping you stay in control on technical descents and during long rides when conditions change.
The Giant SLR 2 40 Carbon Disc WheelSystem complements the bike's endurance character with a balance of efficiency, stability and comfort. Fitted with Giant Gavia Fondo 0 tubeless tyres in a 32mm width, the setup provides impressive grip, puncture resistance and ride quality. The frame also accommodates tyres up to 40mm, giving you the flexibility to run wider rubber for rough roads, cobbles or light gravel exploration.
With its combination of lightweight carbon construction, endurance-focused comfort and premium Shimano Ultegra Di2 components, the Giant Defy Advanced-Ui2 is a versatile road bike designed to help you ride further, stay comfortable and enjoy every mile.
