FX Sport 4 is a carbon fibre 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.
It's right for you if...
You're ready to log big miles, and you prefer the feel of a flat handlebar to the drop bars that come stock on most road bikes. You prioritise comfort and performance equally, and want the simplicity that a 1x drivetrain provides.
The tech you get
A lightweight 400 Series OCLV Carbon frame and fork, a Shimano CUES 10-speed drivetrain with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheel set, wide, fast-rolling Bontrager GR1 Expert gravel tyres and a vibration-absorbing handlebar and ergonomic grips.
The final word
Fast, capable, comfortable. The 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.
