Trek FX Sport Carbon 5 2021
Regular price £1,950.00FX 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 high-quality drive train 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 2x10 Shimano Tiagra drive train with a wide range of gearing, hydraulic disc brakes, hidden mudguard mounts, a lightweight Bontrager alloy wheel set with thru-axles for better responsiveness and control, and a vibration-absorbing handlebar with ergonomic grips.
The final word
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.
