The Domane SL 5 is a lightweight carbon endurance bike that blends all-day comfort with clean, modern simplicity. Built from 500 Series OCLV Carbon, it features all-road 40mm tyre clearance and a streamlined design that gets back to the essence of road riding. A 12-speed Shimano 105 drivetrain delivers precise shifting, while a sleek riser bar adds comfort without cluttering the front end, making it ready for long miles, big days, and light gravel detours.
