ADVANCED SPEED. VERSATILE ADVENTURE.

The 2025 Giant FastRoad AR Advanced 2 is a lightweight, flat-bar road bike built for speed, comfort, and confidence across variable terrain. With a composite frame, wide tyres, and endurance-focused geometry, it’s perfect for urban commuting, fitness riding, or light gravel exploration.

Key Performance Factors

Advanced Composite Frame & Fork

Lightweight and responsive Advanced-grade composite frame with full composite fork delivers quick handling and a smooth, efficient ride.

Reliable Drivetrain

Shimano CUES U6000 1x10-speed drivetrain paired with an FSA Omega AGX+ 42T crank offers simplicity and gear range for road and gravel riding alike.

Confident Control

Tektro HD-R280 hydraulic disc brakes provide reliable stopping power in all conditions, from busy streets to winding paths.

Smooth & Stable Ride

Maxxis Re-Fuse 700x40c tubeless-ready tyres, Giant S-X2 Disc wheels, and a D-Fuse alloy seatpost combine for grip, comfort, and reduced fatigue over long distances.

TECHS & FEATURES

×

ADVANCED COMPOSITE TECHNOLOGY

Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and moulded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

TUBELESS SYSTEM

Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
