"Trek’s best road bike gets faster, lighter, quicker and better"
"When you get on a bike that is fast, quick and communicative but also floats and coddles the rider like a newborn baby, well, that is a special bike. And that is what the new Domane is: Special. A great bike made better. A bike for the modern road rider: Freaking fast, wonderfully comfortable and oh so practical."
"The level of smoothness on the Domane continues to impress, creating an experience akin to being chauffeured around in a luxury sedan. It absorbs all road vibrations, operates quietly and accelerates on flats deceptively quickly… I'll be in for a rude awakening after returning to a road bike without IsoSpeed."
"I took the Domane on my local gravel and some select chunky bits to see how it would fare. The most notable transition from road to gravel was the sense of ease. Usually, when you roll from tarmac to stones, the bike can feel skittish and nervous (rider or bike). The Domane feels stable, and instead of holding your breath, you breathe out."
Whether you're riding solo, with a group, on smooth roads or light gravel – here are the accessories you need to make sure that your Domane is always ready.

Newly refined IsoSpeed soaks up fatiguing bumps and saves weight so you can ride stronger for longer.
Podium-topping speed
Raced to victory on the infamous cobblestones of Paris-Roubaix, the new carbon Domane is faster than ever thanks to new aerodynamic improvements and an ultra-light design.
Light and strong 500 Series OCLV Carbon and a new gram-saving design make this the lightest Domane SL disc ever.
Versatile tyre clearance
Comes equipped with fast-rolling 32 mm tyres, but offers clearance for up to 38 mm tyres so you can confidently ride everything from smooth tarmac to light gravel.
500 Series OCLV achieves a superb balance of light weight, strength, and stiffness that's perfectly suited to the sophisticated frame technologies that distinguish Trek frames.
Performance. Stability. Victory. Trek endurance geometry is a triple threat, maximising control, handling and responsiveness through perfectly tuned rider weight bias.
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.

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.
