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 drive train has a wide range of gears for riding on any terrain. The lightweight aluminium frame has mudguard 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 drive train and brakes. Domane AL 4 Disc is built for miles of fun, fast riding on the road and even light gravel.

The Walkthrough

favorite_borderWhy you'll love it

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

  3. Hydraulic disc brakes give you more precise and consistent stopping power in any conditions
  4. Bigger tyre clearance lets you run wider tyres 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
