Giant FastRoad AR 2 2025 - Road Bike
Key Features:
Lightweight efficiency
High-quality ALUXX aluminium frame and composite fork deliver efficient pedalling power for a smooth, fast ride on variable roads and paths.
Smooth, stable ride quality
Flat handlebar frame geometry creates a more upright riding position for confident handling. Powerful disc brakes offer added control in all conditions. And the combination of a D-Fuse composite seatpost and ErgoContact saddle helps smooth out rough roads.
All-road capabilities
High-volume 40mm tubeless tyres offer the freedom and versatility to ride smooth roads, bumpy bike paths or gravel. Single or double chainring setups are available on different models to suit individual riding style and terrain.
Occasionally, without notice, manufacturers change product design and/or specifications.
