TREK FX Sport SL 4 Hybrid Bike in Onyx Carbon

Season:2025

Brand:Trek

Code:47243BLK

The FX Sport SL 4 is a high-performance carbon fitness bike designed for riders who want the speed and efficiency of a road bike with the control and comfort of flat handlebars. Ideal for long-distance workouts, commuting, and fast-paced group rides, this bike delivers speed and versatility in equal measure.


Key Features

  • Carbon Fibre Performance
    Built with a lightweight 400 Series OCLV Carbon frame and carbon fork for a smooth, responsive ride without excess weight.

  • Simplified 1x Drivetrain
    Shimano CUES 10-speed drivetrain offers a wide range of gears with a single shifter, reducing complexity while maintaining performance.

  • Flat Bar Comfort
    A flat handlebar paired with ergonomic grips provides confident handling and a more relaxed riding position compared to drop bars.

  • Hydraulic Disc Brakes
    Shimano hydraulic disc brakes ensure reliable stopping power in all weather conditions.

  • Tubeless Ready Wheelset
    Lightweight tubeless ready wheels are paired with fast-rolling Bontrager GR1 Expert gravel tyres for speed and grip on various surfaces.

  • Vibration Damping
    The vibration-absorbing handlebar and grips reduce fatigue on longer rides, enhancing overall ride comfort.


Why It Stands Out

  • The 1x drivetrain delivers a clean, intuitive gear setup without sacrificing range.

  • Enjoy the superior ride quality of carbon at a more accessible price point.

  • Perfect for both solo fitness rides and fast-paced group rides—it’s built to keep up.

  • Easily customisable with racks, mudguards, lights, and more to suit your needs.


Ideal For

  • Fitness riders seeking road bike speed with more control

  • Commuters wanting a lightweight, high-performance option

  • Anyone looking for a carbon flat bar bike with simplified gearing
