It's right for you if...

You plan to hop on your bike as much as possible, and even train for races and long charity rides. You want to invest in higher-quality performance parts that will keep pace with you as you continue to hone your road cycling skills.

The tech you get

A 2x10 (20 speed) Shimano Tiagra drivetrain has a wide range of gears for riding on any terrain. The lightweight aluminum frame has fender mounts and a stable Endurance Geometry for a confident ride, and a carbon fork that absorbs road vibration. Plus, tubeless ready rims and hydraulic disc brakes for stopping power in any conditions.

The final word

A solid, comfort-first road bike with upgrades on the parts that matter—like the drivetrain and brakes. Domane AL 4 Disc is built for miles of fun, fast riding on pavement and even light gravel.

The Walkthrough

  1. A light, comfortable frame and quality parts make it an awesome platform for long, fast group rides

  3. Hydraulic disc brakes give you more precise and consistent stopping power in any conditions
  4. Bigger tire clearance lets you run wider tires for more traction and stability on rail trails and other light gravel roads
  5. DuoTrap S compatibility makes it easy to wirelessly track your rides, so you can set goals and watch yourself reach them

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
