Advanced-Grade Composite Carbon Frame

The Giant Defy Advanced 0 features an Advanced-Grade Composite carbon frame, designed to balance low weight, efficient power transfer and comfort for endurance road riding.

Its endurance-focused geometry provides a comfortable riding position without sacrificing responsive handling, making it well suited to long-distance rides, challenging climbs and varied road conditions.

The frame is engineered to provide compliance without relying on complex suspension systems, helping absorb road vibrations while maintaining pedalling efficiency.

Clearance for tyres up to 40mm also provides versatility, allowing riders to choose wider tyres for additional comfort and grip on rougher surfaces.

Advanced-Grade Composite Carbon Fork

The Advanced-Grade Composite carbon fork is designed to complement the frame's endurance characteristics, helping reduce road vibrations while maintaining precise steering.

It features a full-composite OverDrive steerer, providing front-end stiffness and responsive handling when cornering or descending.

A 12x100mm thru-axle provides a secure connection between the fork and front wheel, contributing to steering precision.

Shimano 105 Di2 24-Speed Drivetrain

The Shimano 105 Di2 2x12-speed drivetrain provides precise electronic shifting, making gear changes quick and consistent across a wide range of riding conditions.

A compact 50/34T Shimano 105 chainset is paired with an 11-36T cassette, offering a useful spread of gears for steep climbs, rolling terrain and faster road sections.

The Di2 system uses electronic controls to operate the derailleurs, reducing the effort needed to change gears and providing consistent shifting performance.

Shimano's E-Tube app also allows riders to customise certain shifting functions and settings to suit their preferences.

Shimano 105 Hydraulic Disc Brakes

Shimano 105 hydraulic disc brakes provide consistent stopping power and progressive braking control in varied weather conditions.

The bike features Shimano RT-CL700 rotors measuring 160mm front and rear, offering reliable braking performance for long descents and everyday road riding.

The hydraulic system provides controlled braking with relatively light lever effort, helping riders maintain confidence on technical descents and wet roads.

Giant SLR 2 40 Carbon WheelSystem

The Giant SLR 2 40 Carbon Disc WheelSystem combines lightweight carbon rims with a 40mm rim depth, balancing aerodynamic efficiency with responsive handling.

The wheels feature Giant alloy hubs, Sapim spokes and 12mm thru-axles, providing a secure and dependable setup for endurance road riding.

Their carbon construction helps reduce weight while maintaining stiffness, making them suitable for climbing, accelerating and maintaining speed on longer rides.

Giant Gavia Fondo 0 Tubeless Tyres

The Giant Gavia Fondo 0 700x32c tubeless tyres are designed for endurance road riding, offering a balance of rolling efficiency, comfort and grip.

Their wider profile provides additional cushioning compared with narrower road tyres, helping smooth out rough tarmac and uneven surfaces.

The tubeless setup allows riders to use lower tyre pressures for improved comfort and traction, while reducing the risk of pinch punctures. When used with sealant, smaller punctures can also seal automatically.

Giant Contact SL D-Fuse Handlebar

The Giant Contact SL D-Fuse handlebar features an ergonomic design intended to improve comfort and control during longer rides.

Its D-shaped profile provides additional compliance to help absorb road vibrations, reducing the amount of feedback transmitted through the hands and arms.

An 8-degree flare provides a wider position at the drops, offering additional control when descending or riding over rougher surfaces.

The handlebar is paired with a Giant Contact AeroLight stem, creating a clean cockpit setup with responsive steering.

Giant D-Fuse Composite Seatpost

The Giant D-Fuse composite seatpost features a distinctive D-shaped profile designed to flex slightly under load, helping absorb road vibrations and reduce fatigue on longer rides.

Its carbon construction provides a balance of low weight and compliance, complementing the frame's endurance-focused design.

A 14mm offset helps position the saddle appropriately, while the Giant Approach saddle provides support for extended periods in the saddle.

Built for Endurance Road Riding

With its lightweight carbon frame, Shimano 105 Di2 electronic drivetrain, carbon wheels and vibration-absorbing D-Fuse components, the Giant Defy Advanced 0 is designed for riders who enjoy covering longer distances.

Its combination of endurance geometry, wide tyre clearance and reliable hydraulic disc brakes makes it well suited to sportives, challenging climbs and all-day road adventures.

Occasionally, without notice, manufacturers change product design and/or specifications.
