Zipp 303 Firecrest Tubeless rear wheel is 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.
Deeply rooted in Zipp’s drive to conquer the Spring Classics, the new 303 Firecrest is remade with a purpose-made approach for the demands of modern road bikes.
- Its rim is slightly more bulbous in design than its predecessor, with a 30 mm outside width, a 25 mm internal width, and a 40 mm rim depth.
- The profile provides low drag and an improved transition between rim and tire, boosting aero efficiency on the road.
- The wide rim stance also features less tire deflection for reduced rolling resistance.
- The combination of the wider tire, increased tire volume, and lower tire pressure helps to reduce rider fatigue by smoothing out the ride over imperfect pavement and road conditions.
- Feature a versatile and durable new hubset, the German-engineered ZR1 DB. This hubset has 66 points of engagement for quicker response.
