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
• ABLC Sawtooth dimple design helps manage air flow around the rim, and contributes to create a faster, more stable wheel
• Zipp graphics that scream speed, applied using Zipp’s ImPress direct-print technology to help allow the dimples to do what they were designed to do – improve aero performance
• Includes rim kit decals, nipple washers, tubeless tape, valve and wrench
