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 endurance geometry, wide tires, and carbon fork keep you comfortable when you’re setting distance records.
Domane AL Disc is built in Trek's road race heritage, which means it's a road bike you won't outgrow as your rides get longer and faster.
Any road, any adventure
Disc brakes, extra tire clearance, and mounts for a rack and fenders give it the versatility for any all-road adventure.
Premium alloy frame
Every Domane AL Disc has a lightweight aluminum frame with internal cable routing and smooth welds for race-ready looks and performance.
Going for a long ride? Rack mounts make carrying accessories a breeze.
It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimizes the wheelbase.
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 through the entire ride.
Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximizing control, handling, and responsiveness through perfectly tuned rider weight bias.
Fender mounts allow for full-coverage fenders so you can ride comfortably in less-than-ideal conditions.
Additional Tire Clearance
Additional tire clearance allows Domane to go where no road bike has gone before. Race, ride, explore.

Sizing & Tech
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 retailer.
