Trek FX Sport 4 Road Bike In Matte Onyx Carbon

Season:2025

Brand:Trek

Code:47243BLK

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.

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 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.

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
  • On your left! This fitness bike is more than capable of taking on speedy group road rides
  • It's easy to accessorize with fenders, lights, and more!
