The FX Sport 5 is right for you if…

You’re ready to log big miles, and you prefer the feel of flat handlebars to the drop bars that come 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 FX Sport 5 is perfect for you.

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, Tektro hydraulic flat mount disc brakes, hidden mudguard 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 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

  1. All the performance of an advanced carbon road bike, with the comfort and control that comes from flat handlebars
  2. On your right, roadie! FX Sport 5 is more than capable of taking on speedy group road rides
  3. You can pair FX with your smartphone and send your ride data to your favourite fitness app when you add DuoTrap S
  4. It’s easy to accessorise with mudguards, lights and more!
