FX Sport 6 is the lightest and fastest fitness bike in the lineup.

It has every performance feature of a high-end road bike, with the added benefit of a flat handlebar for additional comfort and control.

The FX Sport 6 is a fitness bike that's every bit as fast and capable as the race bikes found Trek's road lineup

It features a lightweight 400 Series OCLV Carbon frame, a high-quality Shimano GRX 1x drivetrain, and a Bontrager carbon wheelset which makes it the best choice for serious fitness riders with serious goals.

Adding to the bikes high end looks are the cables which are routed internally, which protects them from the elements and adds to the bike's sleek look.

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.

Shimano GRX was designed from the ground up for gravel adventure. With its gravel-specific ergonomics, optimized gearing options, rugged reliability, and quiet, stable drivetrain, GRX sets itself apart from the rest of the component world.

40mm wide gravel tires deliver all-terrain performance. If you don't want to use fenders, you can fit tires up to 42mm wide.

Suspension for your hands. Our exclusive vibration-damping IsoZone material absorbs road bumps and buzz, giving you more control and an incredibly comfortable ride.
