No.9 50d rims are designed to a be a lightweight, aero, stable starting point to build exquisite wheels. They offer an aero advantage over our 30d rims, while offering a stiffer, more robust platform. Fit for long days in the saddle, cutting through the wind and hammering finish line sprints, they’re a perfect all-rounder. These disc brake-specific rims offer clean design and aesthetics. Featuring a wide inner width, they pair well with a variety of tires across the full range of drop bar pursuits. As with all rims we sell, these come with tubeless valves and required tape in the box.
