The final word
The fastest fitness bike. Period. A lightweight OCLV Carbon frame with IsoSpeed, a carbon fork, and a high-performance Shimano 105 drivetrain make FX Sport 6 the ideal ride for anyone who wants to ride ridiculously fast and crush fitness milestones.

Vanishing fender mounts
Discreet mounts accommodate full-coverage fenders for added utility.
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!
Tough Bontrager Hard-Case tires help keep flats from slowing you down.
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.
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.
Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.
