FX Sport 4 is a carbon fiber fitness bike for riders who want the speed of a lightweight road bike with the comfort and control of a flat handlebar.

The 1x drivetrain simplifies shifting without sacrificing gear range, making this high-performance bike perfect for everything from solo workouts to speedy group rides.

The final word - Fast, capable, comfortable. FX Sport 4 has a road-smoothing carbon frame and quality parts that will hold up over serious miles, including the simpler-shifting 1x drivetrain.

Features:
  • The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter
