  • High-value performance

    High-value performance

    Domane AL Disc is built in Trek's road race heritage, which means it's a road bike you won't outgrow as your rides get longer and faster.

  • A better way to produce aluminum

    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.

  • Don’t forget your pedals

    Don’t forget your pedals

    This bike doesn’t come with pedals because you’ll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.

Overview

Domane AL 4 is a versatile road bike that’s ideal for riders looking to go faster and farther on every ride. Its Alpha Aluminum frame and all-day comfort geometry pair with an 11-speed Shimano Tiagra drivetrain for smoother shifting and better range than entry-level builds. With top tube mounts, larger tire clearance, and confident handling, it’s ready for everything from long group rides to adventurous gravel detours.
