It's right for you if...
You want an awesome performance road bike at a great value. You're looking for a carbon bike with a super smooth ride that will help you perform your best on long rides. You also want the added capability and confidence of disc brakes and wider tires.
The tech you get
A 500 Series OCLV Carbon frame with road-smoothing Front and Rear IsoSpeed, a stable Endurance Geometry, powerful flat-mount disc brakes, and a 2x10 Shimano Tiagra drivetrain. Plus, a micro-adjust seatmast, fender mounts, and Tubeless Ready wheels wrapped in wider 700x32 tires. Internal storage and cable routing add to the bike's capability and sleek look.
The final word
Domane SL 4 Disc is the introductory carbon model in the family, but when you make the small jump in price from aluminum models, you get a big jump in tech, including a much lighter frame, Front and Rear IsoSpeed, a full carbon fork, and the added stopping power and tire clearance disc brakes provide.

More choice for all genders
We believe every rider—regardless of gender, body type, riding style, or ability—deserves a great bike. One that gets you excited to hop in the saddle and ride. A bike that makes you want to go faster and farther than ever before. A bike that feels like it was made just for you. Because it was. Trek is introducing the new 2020 Domane to give better fits and more options to female and male riders alike. Historically, we’ve offered smaller frame sizes geared towards women on women’s models exclusively. We’re now offering smaller sizes and more colorways on every single 2020 Domane SLR, SL. A smaller rider, no matter their gender, can now choose from every model we offer in these performance lines. There is no specific women’s offering for these bikes. They’re all women’s bikes. They’re all men’s bikes. Why are we doing this? To give more fit and color options to all riders, regardless of gender or size.
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.
Additional Tyre Clearance
The additional tyre clearance allows the Domane to go where no road bike has gone before. Race, ride, explore.
Performance cable routing
Our sleek, race-optimized cable routing system virtually eliminates friction for the crispest shifting in any conditions. Three years in the making, and well worth the wait.
Flat Mount disc brakes
All-new Flat Mount disc brakes are more elegant, lighter, smaller and cleaner than traditional disc brakes, providing superior performance and stopping power under harsh conditions.
The all-new micro-adjust seatmast is lightweight, strong, super aerodynamic, and easy to use. Even a millimeter change in geometry can alter your speed. Dial in your fastest, lowest-profile position ever with the all-new seatmast.
Fender mounts allow for full-coverage fenders so you can ride comfortably in less-than-ideal conditions.
