This Performance level frame material features 6061 alloy with single-butted tubes to produce strong, lightweight framesets for a variety of different bikes and riding styles.
It’s quick, it’s agile, and it can take you just about anywhere. With flat handlebar positioning, a smooth ride quality, and wide tubeless tyres, FastRoad AR frees you up to ride paved roads, bumpy bike paths and everything in between.
Key Performance Factors
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.
Techs & Features
ALUXX Aluminium Technology
D-Fuse Technology
The D-Fuse seatpost and handlebar were designed to function as a system, absorbing road shocks and vibrations so you can ride further, faster.
OverDrive
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
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.
