Trek FX Sport AL 3

The FX Sport AL 3 is a lightweight, versatile aluminium bike, perfect for exploring the road less travelled. It comes ready for anything, with a reliable and light Alpha Gold Aluminium frame, 10-speed Shimano CUES shifting, go-anywhere Bontrager Girona gravel tyres and hydraulic disc brakes.

Fast and comfortable
Our Active geometry puts you in a slightly more forward position to give you more pedalling efficiency while staying comfortable on long rides.

All-road capable
Wide 42c Girona tyres offer traction and control on tarmac or rough tracks.

Reliable and durable
The Shimano CUES drivetrain offers a hassle-free, low-maintenance performance riders can rely on for the long haul. CUES features Shimano's new LINKGLIDE drivetrain technology for less wear and tear on chains, cassettes and chainrings.

A better way to produce aluminium
Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

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.
