Few wheels can claim the pedigree and speed of Zipp's 404s. These wonder-wheels boast 58mm-deep, dimpled, carbon/aluminum rims for the holy trinity of wind-cheating aerodynamics, gossamer weight and power-boosting lateral stiffness. Plus, Zipp's Multi-Material Co-Molding technology provides extra impact resistance for mile-after-mile durability. And, these top-notch rims are laced to Zipp's precision hubs that boast some of the roundest ball bearings in the industry for maximum speed out on the road. With countless ProTour race victories, world championships and Olympic medals, it's no wonder the 404s are some of the most revered wheels on the planet.
Features and Information
For maximum aerodynamic efficiency, and an incredibly fast ride, all of Zipp's carbon rims have a dimpled outer surface that minimizes drag.
Zipp's Visco-elastic Constrained Layer Control takes away the harsh ride of deep-dish carbon rims by sandwiching a layer of viscous material in between two layers of structural carbon, reducing road vibration by up to 10%, giving you a ride that is both blazingly fast and decadently smooth.
All of Zipp's clincher wheels use their Multi-Material Co-Molding (M2CM) process that seamlessly bonds the aluminum extrusion to the carbon rim for superb braking and extraordinary strength.
