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.

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.

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.

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

Hydraulic disc brakes offer the absolute strongest stopping power even in wet and muddy conditions.

The core of Trek's endurance comfort technology is our IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider. It's a technological revolution.

Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

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 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.

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.

Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.

Bontrager stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.

Discreet mounts accommodate full-coverage mudguards for added utility.
