If you had to choose just one wheel, the 404 Firecrest Carbon Clincher is a savvy and speedy choice. With a 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.
Every Firecrest rim is made by hand at our Indianapolis factory. Having engineering, manufacturing and testing under one roof helps us innovate more quickly while ensuring top quality. The 404 Firecrest Carbon Clincher is where the Firecrest® Revolution began as the first deep-profile carbon clincher design to offer the superior aerodynamics, ride quality, strength and handling of a wider rim body. Yet the 404 Firecrest Carbon Clincher weighs 1,615 grams per set, providing best-in-class performance at a light weight.
At the center of the 404 Firecrest 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. For those looking for a wider gear range, or tackling especially extreme terrain, we now offer our Firecrest Carbon Clincher wheels with a XDR driver body allowing for more cassette options including a 10-42. Optimized flange geometry and spoke hole attachment pattern with Sapim® CX Sprint spokes to optimize torsional and lateral stiffness and robustness.
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, our composites supplier created a heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that our Carbon Clinchers have never had a heat-related failure.
