FX Sport SL 6 is an ultra-light and fast fitness bike. It has every performance feature of a high-end road bike, with the added benefit of a flat handlebar for additional comfort and control. A lightweight 400 Series OCLV Carbon frame, wireless electronic SRAM shifting, and Bontrager carbon wheels make it the best choice for serious fitness riders with serious goals.

Dialed-in to go all day

A slightly shorter reach and taller stack put you in a more upright, balanced position for smooth power and all-day rideability.

Light on weight. Big on performance.

Designed with 400 Series OCLV, the lightweight carbon frame keeps things fast and responsive, so you can accelerate quicker and handle with confidence.

1x drivetrain

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.

Fast, smooth, reliable

With SRAM Apex, you get precise shifting and confident braking for a ride that feels quick, fun, and in control.

Ready for any path

Wide gravel tires keep you rolling fast with added traction and control, while increased clearance lets you take on rougher terrain with ease.

Pack it up, pack it in

Mounts for a top tube bag, rack, fenders and water bottles let you carry everything you need for day-long adventures, fast commutes, and anything in between.
