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.
Lightweight design
A new full carbon fork and updated frame design helps shave around half a pound from the previous generation Domane AL Disc.
Right for any road
Room for bigger tyres let you ride everything from smooth tarmac to most gravel roads in comfort.
Long-haul comfort
A more upright road riding position keeps you comfortable, confident and efficient during long days in the saddle.
Pack it up, pack it in
Mounts for a top tube bag, rack, mudguards and water bottles let you carry everything you need for day-long adventures, fast commutes and anything in between.
Modern ergonomics, premium integration
A modern handlebar with 4 cm of flare between the drops and hoods put you in a more comfortable position, and new hidden cable routing offers premium integration typically found on more expensive models.
High-value performance
The Domane AL Disc is built in Trek's road racing heritage, which means it's a road bike you won't outgrow as your rides get longer and faster.
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.
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.
