'The new Domane SLR is a seriously smooth-riding machine.'

'If you’ve been thinking about a new all-road bike and holding out as one of the sceptics of Trek’s IsoSpeed concept in general, though, feel free to stop sitting on your hands and just go out and ride one. IsoSpeed has never been an empty gimmick, and this latest incarnation certainly does seem to be Trek’s best interpretation to date.'

'I liked the last Domane. But I love this one.'

'We’re truly in a special era in which it’s very difficult to make a bad bike, and even more difficult to stand out among the crowd. The Domane does so here. From its looks to its compliance features, and its geometry that more closely mirrors a race bike without getting absurdly aggressive, the Domane gets a lot right.'

'One of the best bikes you can buy at the moment'

'The third-generation of Trek's Domane is not just the best Domane; it is Trek's best-ever road bike. And one of the best road bikes on the market at the moment. This is the bike most of us should ride. It's entertainingly sharp and sporty, smooth, smart and versatile enough for most forms or road riding, tarmac or gravel. And that's why it's one of the best bikes you can buy at the moment.

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 further 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 colourways 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 colour options to all riders, regardless of gender or size.

T47 Bottom Bracket

Equipped with a threaded T47 bottom bracket. In addition to being super-reliable and easy to service, this system offers extra stiffness for better power transfer and pedalling efficiency.

IsoSpeed decoupler

The core of Trek's endurance comfort technology is our IsoSpeed decoupler, the result of an 18-month study of how a racing bike performs over rough roads, and how that performance affects the rider. It's a technological revolution.

Endurance fit

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.

Endurance geometry

Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximising 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-optimised 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.

Micro-adjust seatmast

The all-new micro-adjust seat mast is lightweight, strong, super aerodynamic and easy to use. Even a millimetre change in geometry can alter your speed. Dial in your fastest, lowest-profile position ever with the all-new seat mast.

Specs Sizing

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.
