Make it your own
Customize your bike with fenders, racks, bottle cages, and more to make it your own.
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.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
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.
Learn moreWide, 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.
