Domane AL 4 Gen 3

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.

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.

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.

A light, comfortable frame and quality parts make it an amazing platform for long, fast group rides
The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly
Hydraulic disc brakes give you more precise and consistent stopping power in any conditions
Bigger tyre clearance lets you run wider tyres for more traction and stability on rail trails and other light gravel roads
DuoTrap S compatibility makes it easy to wirelessly track your rides, so you can set goals and watch yourself reach them

'Its crazily versatile, it can be so many different things, so it's really cool that it then rides so much like a road bike. I was really blown away.'

The endurance geometry, wide tyres and carbon fork keep you comfortable when you’re setting distance records.

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.

Disc brakes, extra tyre clearance and mounts for a rack and mudguards give it the versatility for any all-road adventure.

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 flats for versatility or clipless pedals for control and efficiency.

Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximising control, handling and responsiveness through perfectly tuned rider weight bias.

It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimises the wheelbase.

Going for a long ride? Rack mounts make carrying accessories a breeze.

The additional tyre clearance allows the Domane to go where no road bike has gone before. Race, ride, explore.

We reserve the right to make changes to the product information contained on this site at any time without notice, including with respect to equipment, specifications, models, colours, materials and pricing. Due to supply chain issues, compatible parts may be substituted at any time without notice. The prices shown are the manufacturer's suggested retail prices.

Bike and frame weights are based on pre-production painted frames at time of publication. Weights may vary in final production.

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
