Zipp 404 Firecrest
Naturally, Zipp chose to launch their groundbreaking Firecrest® and Carbon Clincher designs with its most popular and most versatile wheelset, the 404. Its 58mm rim depth is a classic all-around performer that has carried athletes to victory in every kind of event – triathlons, criteriums, breakaways, field sprints and even Grand Tour mountain stages.
Described by many as the most highly anticipated wheelset of all time, the 404 Firecrest Carbon Clincher launched a new era of innovative excellence. Following a full two years of development for its revolutionary rim shape and carbon technology, we’re confident you will find that the 404 Firecrest Carbon Clincher lives up to the hype.
The 404 Firecrest features the the 88/188 hubset, with a 7.5mm-wider bearing stance in the rear hub, the drive-side is canted by 2 degrees for both improved stiffness and greater reliability. For 2013, this venerable wheelset is available in two decal options, the stealthy Beyond Black or the distinctive Classic White decals. Both decal options feature black anodized hubs, black spokes and black nipples.
The 404 Firecrest aero profile is 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 just 1,495 grams per set, putting it among the lightest deep-profile carbon clinchers available.
Designed specifically to account for the differences in airflow patterns between clincher tires and tubulars, the 404 Firecrest Carbon Clincher far exceeds the aero performance of any other clincher wheelset in its class. As Zipp proved with the Paris-Roubaix-winning 303 Tubular, a wider rim offers greater vertical compliance for control and comfort on rough surfaces while increasing lateral stiffness for sprinting and cornering. The same holds true for Firecrest rims with clincher tires. And because the hook beads are farther apart, the tire itself takes on a more stable shape without adding rolling resistance.
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 new heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that Zipp firecrest carbon clincher wheels are THE ONLY carbon clinchers to pass stringent European safety testing WITHOUT limitations on either rider weight or brake pad options.
With the new Firecrest rim shape in Zipp 404 Tubulars and Carbon Clinchers, Zipp wheels make a bigger difference in more ways than ever. Not only is Firecrest more aerodynamic than any other rim design, it improves handling in crosswinds, wheel strength, and overall ride quality.
Every aspect of our 88 and 188 hubs sets a new benchmark. The standard steel bearings are the roundest in the industry. The 17mm axle is the stiffest of any road hub we've tested. When it comes to precision and performance, there's really no comparison.
Advanced Boundary Layer Control (ABLC) refers to the patented, dimpled pattern found on most of Zipp's rims. ABLC smoothes airflow across the rim's surface and is tailored to every model of Zipp wheel. Starting in 2009 Zipp implented the third-generation of ABLC, with up to 4 times more dimples than before.
