Trek Domane AL review: Blurring the line

Sep 7, 2023 · Alvin Holbrook

Big tire clearance and lower weight give the new Trek Domane AL generation 4 all-road bike credibility both on road and on dirt.

From Trek

Right for any road

New 40mm tire clearance (as measured) lets riders comfortably venture from smooth pavement to bumpy backroads and most gravel trails.

Sleek aluminum meets lightweight carbon

The new Domane AL is around half a pound lighter than the previous Domane AL Disc model thanks to a newly redesigned 100 Series Alpha Aluminum frame and a new full-carbon fork.

Mounts for the essentials

Mounts for a top tube bag, rack, and fenders make Domane AL the ideal rig for everything from workday commutes to weekend group rides.

Modern handlebar, premium integration

Domane AL’s cockpit now features a modern road bar for improved ergonomics and control, with a shorter reach and 4mm flare between the hoods and drops. Plus, new hidden cable routing offers premium integration typically found on higher-end models.

Universal Derailleur Hanger (say what?!)

For the first time ever, Domane AL comes with a new thru axle for Universal Derailleur Hanger compatibility. This is the same UDH that comes on Trek mountain bikes, so riders can enjoy cross-category compatibility with all their favorite rides.

Comfortable geometry

Domane’s relaxed endurance geometry keeps riders in a more upright position for all-day comfort.
