FX Sport 5 is a carbon fibre fitness bike for riders who want the speed of a lightweight road bike with the comfort and control of a flat handlebar. A 400 Series OCLV Carbon frame with an IsoSpeed decoupler to smooth out rough roads, a carbon fork, a Shimano 2x10 drivetrain and hydraulic disc brakes make it 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 prioritise 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 mudguard mounts, a Bontrager Montrose saddle and a lightweight Bontrager alloy wheel set 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 line-up. FX Sport 5 has quality parts that will hold up over serious miles, but the 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 for longer.
Why you'll love it
All the performance of an advanced carbon road bike, with the comfort and control that comes from flat handlebars
