With Firecrest’s unparalleled approach to the wheel’s centre of pressure, the 808 Firecrest Carbon Clincher also handles crosswinds with the stability you’d normally associate with a much shallower rim – making the 808 Carbon Clincher ideal for non-disc-legal courses like Kona. Plus, the wide rim shape provides efficient power transfer along with comfort and durability, making it an excellent choice for just about any terrain and riding style.
In addition to Firecrest, all Zipp full-Carbon Clinchers feature an exclusive heat-resistant resin as part of the composite structure. Utilised in the 808 Firecrest Carbon Clincher, this technology prevents spikes in rim temperature and tyre pressure that can impact performance and handling. In fact, heat dissipation is improved so substantially that ours are the only carbon clinchers to pass stringent European safety testing without limitations on rider weight or brake-pad options.
So every rider can tackle even the longest, most technical descents with confidence
|Zipp Firecrest Rim Technology|
|Firecrest - a better wheel in every way|
For every rider, every discipline, and every ability level, aero wheels make a difference. Every test we’ve ever run has confirmed this basic truth and we’ve never seen data from anyone else that argues differently.
With the new Firecrest rim shape in our 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.
Discovered as we developed our carbon clinchers, Firecrest refocused our thinking from the front to the back of the wheel. Previous rim shapes were designed to smooth airflow coming off the tyre, 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 latest 404 Tubular (58mm rim depth) matches the aero performance of the pre-Firecrest 808 (81mm depth). And the new 808 Tubular is faster than any competitor’s 90mm rim.
During the design process, we realised that the advanced mathematics and massive computing power that helped us create a faster wheel could also help reduce the impact of crosswinds on handling. Using computational fluid dynamics (CFD), we’ve discovered subtle variations in rim shape that improve stability without increasing aerodynamic drag. By moving the center of pressure – the focal point of side forces on the rim – to its optimal location near the steering axis, Firecrest offers stable, predictable handling at every wind angle. In real-world conditions, Firecrest rims are markedly more stable than other rims of equal or even shallower depth.
As we discovered with designs like the Paris-Roubaix-winning 303, 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. In both tubular and clincher versions, the wider design better protects tyres and places more rubber on the road while cornering without adding rolling resistance.
