Product Information

Trek Domane AL 3 Disc Road Bike

Trek designed their aluminium Domane range to provide you with a fun and easy way to start enjoying being out and about, riding on the roads. Whether you're looking to get out with your friends or you're looking to do some solo sessions to increase your fitness, the Domane makes getting fit fun whilst making it easy to build your confidence riding on the road. The AL 3 was created by Trek in their top quality workshop, using 100 series alpha aluminium to provide you with a frame that's strong and stiff where it needs to be whilst keeping the overall weight to a minimum.  An added bonus of Trek's AL 3 is that it's also backed by the company's lifetime frame guarantee. By featuring a carbon IsoSpeed fork, the AL 3 is able to provide a smooth ride for you by absoribing vibrations from bumps in the road as well as helping to reduce the overall weight of the bike. Fitted with a Shimano Sora R3000 to offer a lightweight groupset that makes climbing easier and provides you with the gearing you need whether that's riding leisurely solo or cranking up the pace on your local group ride. The Domane aluminium is compatible with rack mounts to make commuting easier with the kit you need as well as having a large tyre clearance that means you can fit mudguards to prevent getting mucky and wet in nasty conditions. Finally, with disc brakes, you've got superior control out on the roads that makes stopping quickly that much easier.

Full Specification



It's Right For You

You're just getting into road cycling, or are looking to upgrade from an older road bike, and want a fantastic ride without an eye-popping price. You want a bike with quality parts and powerful disc brakes that will keep up with you for miles to come. This versatile bike’s smooth, capable ride will get (and keep) you excited to go on longer rides.


The Tech You Get

The Shimano Sora drive train has 18 speeds, with integrated brake/shift levers. It's a lighter parts group than Shimano's introductory groupset and provides a wide range of gears that's great for climbing. The lightweight aluminium frame has a stable Endurance Geometry for a confident ride, disc brakes, a Domane carbon fork, mounts for mudguards and tubeless-ready rims. The stable Endurance Geometry delivers comfort and confidence. The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly.


The Final Word

This bike has lighter parts, an advanced aluminium frame, powerful disc brakes and a comfort-first geometry designed to help you fall in love with road cycling. DuoTrap S compatibility makes it easy to wirelessly track your rides, so you can set goals and watch yourself reach them. Like every Trek bike, it's backed by a lifetime warranty and supported by a wide network.
