Our '606' wheelset has long been a favourite among triathletes and time trialists, combining the speed of the 808 on the rear with the handling and reduced weight of the 404 on the front, making it an ideal pairing for changeable conditions, hilly courses and smaller riders.
If you had to choose just one wheel, the 404 Firecrest should be your choice. With the depth and shape proven in all conditions, it’s the all-around performer and the standard by which all other wheels are measured. Its 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event and situation – every triathlon distance, breakaways, field sprints and hilly finishes.
At the center of the 404 and the 808 is Zipp’s 77/177 hubset with best-in-class durability and improved bearing protection with no pre-load adjustment needed. The result is improved stiffness, durability, simplicity and versatility.
Heavy continuous braking on carbon surfaces can cause spikes in rim temperature and tire pressure that impact performance and handling – especially with clincher tires. To solve this challenge, Zipp's U.S.-based composites supplier created a heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that their Carbon Clinchers have never had a heat-related failure.
