"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."

"Smooth operator"

"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."

"Fast on all terrain"

"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."
