A NEW CHAPTER IN SPEED.
Naturally, Zipp chose to launch their groundbreaking Firecrest® and Carbon Clincher designs with their most versatile wheels, the Zipp Z404 Firecrest Carbon Clincher Bicycle Wheel. Its 58 mm 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.
In fact, Zipp’s first full-carbon clincher wheelset, the 404 Firecrest Carbon Clincher Front Bicycle Wheel, has been described as the most heavily anticipated wheelset of all time. And following two years of development for its revolutionary rim shape and carbon technology, Zipp’s confident that the 404 Firecrest Carbon Clincher lives up to the hype.
The 404 Firecrest Rear Bicycle Wheel features the 188 hubset, with a 7.5mm-wider bearing stance in the rear hub, and a driveside hub canted by 2 degrees for improved stiffness and reliability. For 2013, the this 404 Firecrest Rear Bicycle Wheel comes in stealthy Beyond Black decals and features black anodized hubs, black spokes and black nipples.
Its 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 1,525 g/wheelset, 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 ours are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options.
- Recommended and approved brake pads. These brake pads have been tested and approved by Zipp for use with their tubular and all carbon clinchers. Failure to comply with these recommendations could negate your warranty.

- Firecrest - With the new Firecrest rim shape in Zipp’s 404 and 808 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.
- ABLC™ (Aerodynamic Boundary Layer Control) - Advanced Boundary Layer Control (ABLC) refers to the patented and instantly recognizable dimpled pattern found on most Zipp rims. ABLC smoothes airflow across the rim's surface and is tailored to every model from the 202 to the Sub9 disc. 2009 sees the third-generation of ABLC, with up to 4 times more dimples than before.
- VCLC™ (Visco-Elastic Constrained Layer Control) - Visco-Elastic Constrained Layer Control (VCLC) uses a vibration-absorbing material sandwiched between layers of rigid carbon laminate in the rim. When the wheel receives an impact from the road, much of the shock is absorbed by the VCLC system, delivering a 10% reduction in vibration.
- 88/188 Hub Technology - Every aspect of Zipp’s 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 they've tested. The wire EDM-cut hub internals are the most precise. The SHIFT spoke hole technology is the most durable. When it comes to precision and performance, there's really no comparison.
