Zipp’s 303 Firecrest Carbon tubeless rims are designed for the real world… a world of imperfect conditions, road surfaces, and elements where the bottom line is simple. Efficiency = speed. It’s faster, lighter, and more capable over varied terrain—whether the surface is pavement in all its conditions or no pavement at all.
- 30mm outside width, a 25mm internal width, and a 40mm rim depth
- The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road
- Includes rim kit decals, nipple washers, tubeless tape, valve and wrench
