Trek FX Sport SL 6

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.

• A fitness bike that's every bit as fast and capable as the race bikes found in our road lineup
• The wireless 1x drivetrain delivers precise shifting and keeps cables to a minimum
• Its hydraulic brake cables are routed internally, protecting them from the elements and adding to the bike's sleek look
• It's easy to accessorize with fenders, lights, and more!

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.

Just-right geometry

The all-new FX Sport has slightly less reach and slightly more stack than previous models for a more comfortable yet active and fast riding position.

400 Series OCLV

Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
