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 they’re tubeless ready so you get a smoother ride, more grip, and fewer flat tires. 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.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All our bikes are designed for best-in-class weight and ride quality.
