2021
Building fitness and taking care of your health has never been more fun. This lightweight flyer combines the agility of a road bike with the added confidence and control of a flat handlebar setup.
The perfect balance of road bike speed and city bike versatility. Built on a lightweight ALUXX SL aluminum frameset with a smooth-riding composite fork, this new flat-bar road bike puts the rider in a comfortable position that’s smooth and efficient. The D-Fuse seatpost helps smooth out rough roads, and ergo bar ends keep your hands comfortable on longer rides. The fast-rolling wheels can fit high-volume tires up to 32mm in width, and powerful disc brakes give you added control in all types of weather, and easy-to-use rack mounts make FastRoad SL a smart choice for commuting, fitness riding and weekend adventures.
