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. An IsoSpeed decoupler smooths out rough roads and the 1x11 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 prioritize comfort and performance equally, and want the simplicity a 1x drivetrain provides.
The FX Sport Carbon 4 uses a lightweight OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a Shimano GRX 1x11 drivetrain with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheelset, and ergonomic grips. Plus, its easy to accessorize with fenders, 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 drivetrain provides.
FEATURES:
- The 1x drivetrain 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 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 favorite fitness app when you add DuoTrap S
