FX Sport AL 3 is a lightweight, versatile aluminum bike, perfect for exploring the path less traveled. It comes ready for anything, with a reliable and light Alpha Gold Aluminum frame, 10-speed Shimano CUES shifting, go-anywhere Bontrager Girona gravel tires, 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 tires offer traction and control on paved or unpaved paths.

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 aluminum

Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum 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.
