Few carbon wheels can claim the pedigree and speed of Zipp's 404s. These wonder-wheels boast 58mm-deep, dimpled, full-carbon rims for the holy trinity of wind-cheating aerodynamics, gossamer weight and power-boosting lateral stiffness. Plus, Zipp's Carbon Bridge 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.
Carbon fiber is renowned for its outstanding stiffness, vibration-damping ride quality and out-of-this-world lightness. However, it does not have as much impact resistance as aluminum. Zipp solves this issue and furthers their reputation for making some of the world's best functioning wheels with their Carbon Bridge technology. Kevlar threads woven through the carbon in the prime impact zones boost the rim's impact strength by an outstanding 28%. Carbon Bridge technology means you can ride your Zipps for years to come over the roughest roads with the confidence that you have some of the fastest and strongest wheels going.
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.
