The tech you get
A lightweight 400 Series OCLV Carbon frame with a carbon fork, a 1x Shimano GRX/SLX drivetrain with a wide range of gearing, hydraulic disc brakes, hidden fender mounts, a lightweight Bontrager Aeolus Elite 35 carbon wheelset with high-quality tubeless-ready Bontrager GR1 Team Issue gravel tires, and a vibration-absorbing handlebar with ergonomic grips.
The final word
The fastest fitness bike. Period. A lightweight OCLV Carbon frame and fork, a high-performance 1x drivetrain, and a light and responsive carbon wheelset make FX Sport 6 the ideal ride for anyone who wants to ride ridiculously fast and crush fitness milestones.

Make it your own
Customize your bike with fenders, racks, bottle cages, and more to make it your own.
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.
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.
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.
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.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
