Regular price £1,775.00FX 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 tech you get
A lightweight OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a Shimano GRX 1x11 drive train with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheel set and ergonomic grips. Plus, it's easy to accessorise with mudguards, lights and more!
The final word
Fast, capable, comfortable. This bike has a road -smoothing carbon frame and quality parts that will hold up over serious miles, but what really sets this model apart is the simpler shifting experience the 1x11 drive train provides.
