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 expect your bike to grow with you as you advance in speed and distance.
The tech you get
A lightweight 400 Series OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a carbon fork, a 20-speed Shimano Tiagra drivetrain, Shimano hydraulic flat-mount disc brakes, hidden fender mounts, a Bontrager Montrose saddle, and a lightweight Bontrager alloy wheelset with front and rear thru-axles for better responsiveness and control.
The final word
A fitness bike that's every bit as fast and capable as the race bikes found in our road lineup. FX Sport 5 has quality parts that will hold up over serious miles, but real value of this model comes in the OCLV Carbon frame: it's light, fast, and it has IsoSpeed—a decoupler at the seat tube/top tube junction that absorbs fatiguing bumps from the road so you can stay stronger longer.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
