Trek FX Sport SL 5

FX Sport SL 5 is the carbon fitness bike designed for those who want the speed of a road bike without giving up the control and comfort of a flat handlebar. Lightweight, responsive and incredibly versatile, it’s perfect for intense training, fast commuting and full‑gas group rides.

The high‑performance carbon frame absorbs road vibrations and gives you a smooth, precise riding feel. The 1x drivetrain offers a wide gear range with a single shifter: fewer levers, less complication, more intuitive and reliable shifting in every situation.

The hydraulic disc brakes deliver consistent power and modulation, even in the rain, while the tubeless ready rims let you fit faster, more puncture‑resistant tires, improving comfort and speed.

If you’re looking for a fast, modern, do‑it‑all fitness bike, the FX Sport SL 5 is the ideal choice to take your training – and your fun – to the next level.
