Domane AL 4 Disc | Trek Bikes (INE)

Overview

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.'

Domane AL 2

Features

Every Domane AL Disc has a lightweight aluminium frame with internal cable routing and smooth welds for race-ready looks and performance.

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.

Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks and maximum user friendliness.

As befits the world’s most advanced endurance racing bikes, we’ve developed the world’s most stable racing geometry. Still racy, but with a slightly higher head tube for better stability and greater comfort throughout the entire ride.

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

Mudguard mounts allow for full-coverage mudguards so you can ride comfortably in less-than-ideal conditions.

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.
