The FX Sport 4 is a carbon fiber fitness bike designed for riders who want to combine the speed and lightness of a road bike with the comfort and control of a straight handlebar.
The 1x drivetrain simplifies shifting without sacrificing gear range.
This high-performance bike is therefore perfect for everything from solo workouts to fast group rides.
This is for you if...
You want to ride long, but you prefer the feel of a straight handlebar rather than the curved handlebars found on most road bikes.
Comfort and performance are both important to you, and you love the simplicity of a 1x drivetrain.
