Overview

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 want the simplicity a 1x drivetrain provides.

The tech you get

A lightweight 400 Series OCLV Carbon frame and fork, a Shimano Deore 1x drivetrain with a wide-range cassette, Shimano hydraulic disc brakes for all-weather stopping power, a lightweight tubeless ready wheelset, wide, fast-rolling Bontrager GR1 Expert gravel tires, and a vibration-absorbing handlebar and ergonomic grips.

The final word

Fast, capable, comfortable. This bike has a road -smoothing carbon frame and quality parts that will hold up over serious miles, including the simpler-shifting 1x drivetrain.

1x drivetrain

A 1x drivetrain means more versatility, simpler shifting and less things to go wrong. You still have a wide range of gears, but with lighter and more intuitive shifting. Everything you need and nothing more.

Just-right geometry

The all-new FX Sport has slightly less reach and slightly more stack than previous models for a more comfortable yet active and fast riding position.

400 Series OCLV

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.

FX carbon fork

Lightweight, full carbon fork soaks up hand-numbing road vibration for a more comfortable ride.

Hydraulic disc brakes

Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.

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.

DuoTrap S compatible

DuoTrap S (sold separately) 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.

Sleek cable integration

Cables are routed directly into the head tube and through the bike's tubes for a clean look that prevents cables and housing from getting dirty.

Blendr stem

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

Wide, grippy tires

40mm wide gravel tires deliver all-terrain performance. If you don't want to use fenders, you can fit tires up to 42mm wide.

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 tire pressure for increased traction and comfort without the threat of pinch flats.

Hidden rack and fender mounts

Carry more and stay drier when you add a Bontrager rack and fenders. We recommend Bontrager NCS-1 fenders in size large. For a rack, simply follow Bontrager’s rack sizing guidelines for a perfect fit.

Frame bag mounts

Going for a long ride? Pack all the nutrition and gear you need by adding a Bontrager frame bag using the integrated mounts on the underside of the top tube.
