FX Sport 6 is the lightest and fastest fitness bike in the line-up. It has every performance feature of a high-end road bike, with the added benefit of flat handlebars for additional comfort and control. A lightweight 400 Series OCLV Carbon frame with a road-smoothing IsoSpeed decoupler and an advanced Shimano drive train make it the best choice for serious fitness riders with serious goals.

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.

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