Imagine a quick and agile road bike but with greater versatility. With flat handlebar positioning, smooth compliance and wide tubeless tires, FastRoad AR frees you up to ride paved roads, bumpy bike paths and everything in between.
Key Performance Factors
Lightweight efficiency
High-quality ALUXX aluminum frame and composite fork deliver efficient pedaling 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 ErgoMax saddle helps smooth out rough roads.
All-road capabilities
With clearance for high-volume tubeless tires (up to 42mm), riders have 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.
Highlights
A lightweight, strong and durable ALUXX aluminum frame is designed specifically for a flat handlebar to put the rider in a more stable upright position compared to drop bars. The composite fork minimizes weight and helps absorb road shocks and vibrations. Dropped seatstays and a D-Fuse composite seatpost add compliance in the rear, and ergo grips keep your hands comfortable on longer rides. High-volume 40mm tubeless tires and powerful disc brakes give you added control in all types of weather. Integrated rack mounts make it a smart choice for commuting, fitness riding and weekend adventures.
