Zipp 404 Firecrest Product Information. Zipp's first full-carbon clincher wheel has been described as the most heavily anticipated wheel of all time. And following two years of development for its revolutionary rim shape and carbon technology, theyre confident that the 404 Firecrest Carbon Clincher lives up to the hype. Yet the 404 Firecrest Carbon Clincher weighs just 1590grams, 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 wheel 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.
To solve this challenge, our U. Based composites supplier created a new heat-resistant resin exclusively for Zipp. This technology improves heat dissipation so substantially that theirs are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake pad options.Firecrest® A better wheel in every way. Zipp's proprietary Firecrest® rim rewrote the fundamentals of wheel making, resulting in improved aerodynamics, ride quality, wheel strength and stability in even the strongest of crosswinds. As a result, the entire Firecrest family of wheels makes a bigger difference in more ways than ever. More Speed Firecrest technology, discovered as they developed their Carbon Clinchers, refocused their thinking to concentrate not only on the front half of the wheel, but also the back half. Previous rim shapes were designed to smooth airflow coming off the tire, and tapered inward from the widest point of a toroidal bulge.
But Firecrest rims have a less pronounced bulge and maintain a near-constant width almost all the way to the spoke bed. Without giving up the proven benefits of the toroidal shape, Firecrest is the first aero profile that effectively controls airflow around the back half of the wheel. The performance benefits are substantial. With Firecrest the 404 Firecrest Tubular (58mm rim depth) matches the aero performance of the pre-Firecrest 808 (82mm depth).Zipp's Firecrest rim shape improves stability by moving the wheels center of pressure aft and downward to sit almost directly over the steering axis, where wind-induced steering torque has a minimal effect. Using computational fluid dynamics (CFD) software, Zipp have discovered subtle variations in rim shape that improve stability without increasing aerodynamic drag. With the 404 Firecrest Carbon Clincher, they have achieved a near neutral steering torque.
In real-world conditions, Firecrest rims are markedly more stable than other rims of equal or even shallower depth. More Strength As Zipp discovered when developing the Zipp 303 to thrive under unforgiving conditions at the Spring Classics, a wider rim increases lateral stiffness for sprinting and cornering yet offers greater vertical compliance for more control, comfort, and durability on rough surfaces. The same holds true for Firecrest rims.
The 404 Firecrest is a proven performer on the open road in both tubular and Carbon Clincher versions, the wider design places more rubber on the road while cornering without adding rolling resistance. Now, add to that to their Carbon Clincher technology. Zipp's exclusive resin, based on materials used in motorsports braking systems, effectively tolerates the incredible spikes in heat caused by braking to provide you with reliability and stopping power. Combine that with our Tangente Platinum brake pads and you have unmatched performance, all with the ease of use of a clincher. Carbon Clinchers - A new chapter in speed Zipp Carbon Clinchers have been described as the most heavily anticipated wheels of all time.During the two-year development process, Zipp designed new clincher-specific approaches to prototyping, testing, materials, and manufacturing. The end result is worth the wait. To solve this challenge, chemists and engineers from their composites supplier made repeated visits to Zipp and developed an exclusive heat-resistant resin based on the materials used in motorsports brake systems. This proprietary technology improves heat dissipation so substantially that all Zipp Carbon Clinchers pass stringent CEN safety standards without any limitations on rider weight or brake pad choices a certification that no other full-carbon clincher wheelsets have achieved.
Optimized aerodynamics Wind tunnel development is a cornerstone of how Zipp creates the worlds fastest wheels. Using semi-structural prototypes, we can quickly and accurately evaluate dozens of potential rim shapes. But the prototyping technology that works for tubulars cant support fully inflated clinchers. So they developed an entirely new system where plastic skins are applied to a fully structural interior skeleton. This allowed us to refine carbon clincher rim shapes that perfectly match the distinct airflow patterns created by clincher tires.This process led directly to the Firecrest rim shape that has improved aerodynamics, stability, strength, and comfort in our tubular and clincher wheels. The added width between the clincher hook beads increases air volume in the tire, which means a lower chance of pinch-flatting. And with our exclusive heat-resistant resin, Tangente cork composite brake pads, and angled braking surfaces, Zipp Carbon Clinchers provide smooth, pulsation-free stopping power under all condition. The 404 Firecrest Carbon Clincher is built with a the latest iteration of their 188 rear hub, the V9, along with new spoke-lacing pattern for the rear wheel - refinements that result in improved stiffness and durability. The new 188/V9 hub has larger precision Swiss steel bearings for increased durability. Our new virtual 3 cross lacing on both sides of rear wheel improves stiffness, achieving 3 cross stiffness in a 2 cross pattern with a new spoke geometry. The 188/V9 has 25 percent more torsional stiffness than a leading competitive hub. This measure of stiffness is crucial for the direct power transfer to the rear wheel for out-of-the saddle sprints and climbs. The new hub also is laterally (side-to-side) stiffer that its rival or predecessor. Continental Grand Prix GP-5000 Tires. Continental's Grand Prix 5000 Road Tire is a high-performing all-rounder road tire featuring even better versions of Black Chili tread compound and tear-resistant Vectran Breaker technology, as well as two new technologies: Lazer Grip and Active Comfort.
The GP5000's Lazer Grip technology delivers more cornering traction from day one - no break-in time required thanks to its micro profile structure that reach over the shoulder of the tire. Integrated into the 3-ply/330tpi casing of the Grand Prix 5000, Active Comfort technology provides stiffness in the sidewall and flexibility under the tread for greater vibration dampening and excellent ride comfort.

So, you're inevitably wondering what's new in the world of Zipp? From its wheels to its brake pads, 2013 sees a complete reinvent across the board. And for the Tangente Platinum Pro Evo Brake Pads, Zipp has improved nearly every aspect over its prior iterations.
Now, when we think of brake pads, we're forced to examine their explicit function -- braking. And, as we all know, the functionality of braking is measured by braking power -- something that has long plagued carbon braking surfaces, both tubular and clincher. Challenging this preconception, Zipp increased the surface area of the new Tangente pads, accordingly increasing their braking power by around 10%. Running a close second to braking power is that of pad durability, and this where Zipp achieved the largest headway. The new Tangente pads feature a 1mm reduction in their width from the holder.
This increases clearance for larger tires, wider rims, and the ever-growing integrated brake systems. Additionally, while the width is decreased, the pads' radial height is increased. This plays into the larger surface area that we mentioned, accordingly increasing the pad life of the Tangente. And just importantly, this new dimensional design spreads out heat over a larger area of the braking surface and rim.
So, basic logic tells us that a lower rim temperature will increase the braking effectiveness and durability of the pads. You'll also find that these Tangente pads feature a new groove design. Well, Zipp says that the grooves improve rim temperatures and also braking power in wet conditions.
Essentially, the grooves sweep water off of the rim, while also channeling air over it. So, you can expect a drier and cooler braking surface in nearly any conceivable condition.The Zipp Tangente Platinum Pro Evo Brake Pads are available in the color Grey and in both Campagnolo and Shimano/SRAM brake pad holder compatibilities. Please note that each set comes with two pads, enough to replace one brake.
These pads have not been approved for aluminum braking surfaces. Compatible with Shimano, Campagnolo brakes. Recommended for use with carbon road wheelsets.Each package includes 2 brake pads.
