Description
The Trek 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. Built with Trek’s premium 400 Series OCLV Carbon, this bike is incredibly light, dampens road vibrations, and offers a stiff, responsive feel for fast workouts or long-distance commutes.
What sets the FX Sport 4 apart is its 1×11 Shimano Deore drivetrain. By eliminating the front derailleur, Trek has made shifting simpler and more reliable while still providing a wide range of gears for tough climbs. Combined with hydraulic disc brakes for ultimate stopping power and high-performance gravel-ready tires, this bike is as capable on light gravel paths as it is on smooth tarmac.
Why you’ll love it:
Full Carbon Frame & Fork: Lightweight 400 Series OCLV Carbon makes the ride smooth, fast, and agile.
Simplified 1×11 Drivetrain: Shimano Deore 1x system offers all the gears you need and none you don’t.
Hydraulic Disc Brakes: Superior braking performance that gives you total confidence in any weather condition.
Gravel-Ready Tires: Wide, fast-rolling Bontrager GR1 Expert tires provide extra grip and stability on varied surfaces.
Fitness-Ready Features: Compatible with DuoTrap S to track your ride data and equipped with hidden fender mounts.
