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.

Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power even in wet and muddy conditions.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Lightweight fork with carbon fibre legs soaks up hand-numbing road vibration.
DuoTrap S compatible
DuoTrap S integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.
Tough Bontrager Hard-Case tyres help keep punctures from slowing you down.
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for road wheels. When you go tubeless with TLR, you can run lower tyre pressure for increased traction and comfort without the threat of pinch flats.
IsoZone handlebar and grips
Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.
Hidden mudguard mounts
Discreet mounts accommodate full-coverage mudguards for added utility.
