The Domane+ SLR 9 is our best category-redefining carbon e-road bike that doesn't look, fit or feel like a standard e-bike. It's built on an 800 Series OCLV Carbon frame that hides a compact and refined motor to elevate your ride with natural-feeling assist. The motor quietly blends in with the elements, all but disappearing under you on peaceful solo spins and club rides, so you stay more connected to the experience while enjoying extra power for crushing climbs and long, epic adventures. Adding the cherry on top, it's equipped with the most premium parts the industry has to offer, like Shimano's top-tier wireless electronic drivetrain – Dura-Ace Di2.
