Giant Defy Advanced 2 2026 - Road Bike









The Giant Defy Advanced 2 follows a “less is more” approach to endurance road cycling. Stripping away unnecessary gimmicks, Giant has created one of the lightest frames in its class, delivering a refined balance of responsiveness and comfort. The endurance geometry places you in a relaxed yet efficient riding position, helping you stay fresher for longer on big mileage days.
Key Features:
- Advanced-grade composite frame with endurance geometry and thru-axles
- Advanced-grade composite fork with full-carbon OverDrive steerer
- Shimano 105 2x12-speed drivetrain
- Shimano 105 hydraulic disc brakes with 160mm rotors
- Giant P-R1 Disc wheelset with Gavia Fondo 32c tubeless tyres
- D-Fuse seatpost and Contact SL D-Fuse handlebar reduce road buzz
- Available with 0% APR finance
Constructed from Advanced-grade composite, the frame and fork are specifically tuned to absorb road vibrations without dulling the ride. Giant’s D-Fuse technology plays a central role in this smooth ride quality. The composite D-Fuse seatpost and Contact SL D-Fuse handlebar are designed to flex in a controlled manner, reducing fatigue on rough roads, broken tarmac, and cobbles. The handlebar’s ergonomic shape and subtle flare improve control and comfort during long hours in the saddle.
The Shimano 105 2x12-speed drivetrain offers smooth, precise shifting with a wide gear range that’s perfectly suited to endurance riding. A compact 50/34 chainset paired with an 11–36T cassette gives you the versatility to spin up steep climbs and maintain a comfortable cadence on long, rolling roads. Shimano 105 hydraulic disc brakes provide confident, predictable stopping power in all conditions, adding reassurance on fast descents and wet rides.
Rolling on Giant P-R1 Disc alloy wheels, the Defy Advanced 2 is optimised for high-volume tubeless tyres. Fitted with Giant Gavia Fondo 700x32c tubeless tyres as standard, it offers excellent grip, stability, and comfort, with clearance for tyres up to 38mm if you want even more cushioning and versatility.
The OverDrive steerer system enhances front-end stiffness for precise handling, while thru-axles front and rear improve overall stability and braking performance. Finishing touches such as the Giant Contact AeroLight stem and comfortable Giant Approach saddle complete a well-rounded, endurance-focused build.
Whether you’re training for sportives, tackling long weekend rides, or exploring rougher back roads, the Giant Defy Advanced 2 is designed to help you ride further and more comfortably.
