The Domane AL 4 is a versatile road bike for riders who want to go faster and farther on every ride. The Alpha Aluminum frame and comfortable all-day geometry feature a Shimano Tiagra 11-speed drivetrain that shifts more smoothly and offers a wider gear range than entry-level models. With top-tube mounts, room for wider tires, and a familiar, confident ride feel, this bike is right at home on long group rides, but it also shines on adventurous gravel rides.

Lightweight design
A new full-carbon fork and an improved frame design together save nearly 250 grams compared with the previous-generation Domane AL Disc.

For any road surface
There is room for wider tires so you can ride comfortably on any kind of surface, from smooth asphalt to rough gravel roads.

Comfort on long rides
A more relaxed riding position helps you stay comfortable, enjoyable, and efficient while pedaling through long days in the saddle.

Loaded and ready
With mounts for a top-tube bag, rack, fenders, and bottle cages, you can bring everything you need for long adventure day rides, fast commutes, and everything in between.

Modern ergonomics, superb integration
A modern handlebar with a four-centimeter reach between the brake hoods and the drops puts you in a more comfortable riding position. In addition, the hidden cable routing creates a sleek integration usually found only on much more expensive models.

High-quality performance
The Domane AL Disc comes from Trek’s rich heritage, and that makes it a road bike that keeps going smoothly, even as your rides get longer and the pace picks up.
