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

Hidden mudguard mounts
Discreet mounts accommodate full-coverage mudguards for added utility.
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 tyre pressure for increased traction and comfort without the threat of pinch flats.
Tough Bontrager Hard-Case tyres help keep punctures 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 even in wet and muddy conditions.
