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 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 wheelset, wide, fast-rolling Bontrager GR1 Expert gravel tires, and a vibration-absorbing handlebar and ergonomic grips.

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.

Why you'll love it

1. The 1x drivetrain delivers a wide range of gearing with the simplicity of a single shifter
2. You get the superior ride quality of carbon without the bank-breaking price
3. On your left! This fitness bike is more than capable of taking on speedy group road rides
4. It's easy to accessorize with fenders, lights, and more!
