Zipp 303 firecrest carbon clincher disc rear wheel performance wheels
In developing the original 303 wheelset zipp discovered that a wider rim increases lateral stiffness for sprinting and cornering while also providing greater vertical compliance for greater control comfort and durability that wider rim profile led us to develop our firecrest technology which revolutionized aerodynamic efficiency and stability for carbon wheels the proprietary firecrest rim shape optimizes the aerodynamic profile of the front half and heres the revolutionary part the ba
