Overview
It's right for you if...
You want the most capable bike on the tarmac that doesn't back down from endurance race days, and you're not willing to settle for less. You're looking for the most advanced endurance road bike frame we offer, with the added benefit of a wireless electronic Shimano Dura-Ace Di2 drivetrain for fast, precision shifting in any condition.
The tech you get
An ultralight and refined 800 Series OCLV Carbon frame and fork with rear IsoSpeed, integrated internal storage, and top tube mounts. It's equipped with a wireless Shimano 2x12 wireless Dura-Ace Di2 electronic drivetrain, powerful flat-mount disc brakes, Aeolus RSL 37 carbon wheels, and a Bontrager Pro IsoCore handlebar that reduces vibrations from the road by 20% over a standard carbon bar.
The final word
Our highest-end Domane carbon frame, with the meticulous shifting that comes only from wireless Shimano Dura-Ace. You're getting tech that provides a real advantage in comfort, reliability, and speed during all-day adventures, competitive group rides, or long races.
Why you'll love it
- The sleek all-new 800 Series OCLV Carbon frame saves weight and gives you more free speed thanks to updated Kammtail tube shapes
- Shimano's cream of the crop Dura-Ace Di2 drivetrain provides the pristine and crisp shifts you need, while keeping your setup lightweight
- Road-smoothing rear IsoSpeed absorbs fatiguing bumps in the road to keep you comfortable through the longest miles and hardest race days
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear, while top tube mounts let you cleanly bolt on a bag for all day adventures
"The original racer, yet massively versatile"
"The ride is simply sublime. Its balance between smooth, vibration-eliminating comfort, sharp handling, and out-and-out speed combines with an ability to get off the beaten track."

"Smooth operator"
"The level of smoothness on the Domane continues to impress, creating an experience akin to being chauffered 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."
