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. An IsoSpeed decoupler smooths out rough roads and the 1x11 drive train simplifies shifting without sacrificing gear range, making this high-performance bike perfect for everything from solo workouts to speedy group rides.

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 drive train provides.

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!

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.
- The 1x drive train delivers a wide range of gearing with the simplicity of a single shifter
- You get the superior ride quality of carbon without the bank-breaking price
- IsoSpeed - a decoupler at the seat tube/top tube junction that absorbs fatiguing bumps from the road so you can stay stronger for longer
- On your left, roadie! This fitness bike is more than capable of taking on speedy group road rides
- You can pair FX Sport with your smartphone and send your ride data to your favourite fitness app when you add DuoTrap S

1x drive train
A 1x11 drivetrain means more versatility, simpler shifting and fewer things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.
