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.

Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.
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 tires help keep flats from slowing you down.
Tubeless Ready rims
Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!
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.
