It's equipped with a wireless Shimano 2x12 wireless Dura-Ace Di2 electronic drivetrain, powerful flat-mount disc brakes, Aeolus Pro 37 carbon wheels and a Bontrager Pro IsoCore handlebar that reduces vibrations from the road by 20% over a standard carbon bar.

Why you'll love it

  1. The sleek all-new 800 Series OCLV Carbon frame saves weight and gives you more free speed thanks to updated Kammtail tube shapes
  2. Shimano's cream of the crop Dura-Ace Di2 drivetrain provides the pristine and crisp shifts you need, while keeping your set-up lightweight
  3. The road-smoothing rear IsoSpeed absorbs fatiguing bumps in the road to keep you comfortable through the longest miles and hardest race days
