It's right for you if...

You want the fastest fitness bike you can get—one that can hold its own with any road bike out there. You want to keep up with faster group rides, put on more miles, set new Strava PRs, and leave a pack of roadies in your dust as you sprint to the town line.

The tech you get

A lightweight 400 Series OCLV Carbon frame with a road-smoothing IsoSpeed decoupler, a carbon fork, a 2x11 Shimano 105 road drivetrain with a wide range of gearing, hydraulic disc brakes, hidden fender mounts, a lightweight Bontrager alloy wheelset with thru-axles for better responsiveness and control, and a vibration-absorbing handlebar with ergonomic grips.

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.
