Description

At 765g, the new 202 is the lightest entry in the Firecrest Carbon Clincher lineup. The Zipp® 202 Firecrest Carbon Clincher retains the classic 32 mm rim depth of its predecessor though, with the Firecrest profile, now has a wider 25.4 mm max rim width. The results redefine what’s possible with a do-it-all classic road wheel.

Zipp’s two most profound wheel innovations, the Firecrest rim shape and Carbon Clincher technology, form the foundation of the new 202 Firecrest Carbon Clincher. Firecrest rims have a near-constant width from brake track to spoke bed to improve aerodynamics and better control airflow. We used Computational Fluid Dynamics software analysis to maximize aerodynamics and minimize wind-produced torque, resulting in a 202 Firecrest Carbon Clincher that is faster and better handling than a classic road wheel. Our Firecrest rim shape improves stability by moving the wheel’s center of pressure to sit almost directly over the steering axis, where wind-produced steering torque has a minimal effect.

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 we developed our Carbon Clinchers, refocused our 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. At 615grams, the 202 Firecrest Carbon Clincher (32mm rim depth) is the lightest in Zipp’s Carbon Clincher lineup and is a plucky all-around performer that floats up mountains and provides superior aerodynamics on the flats and descents.

Zipp used Computational Fluid Dynamics (CFD) post-processing capabilities to maximize aerodynamics and minimize wind-induced steering torque, resulting in a 202 Firecrest Carbon Clincher that is faster and better handling than a classic box-section road wheel. Zipp’s Firecrest rim shape improves stability by moving the wheel’s center of pressure aft and downward to sit almost directly over the steering axis, where wind-induced steering torque has a minimal effect.

More Stability
During the design process for Firecrest, we realized 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) software, 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. With the 202 Firecrest Carbon Clincher, we’ve 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 we 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 303 Firecrest is a proven performer on the open road, cobblestones or rough cyclocross courses. In both tubular and Carbon Clincher versions, the wider design places more rubber on the road while cornering without adding rolling resistance. The new 202 Firecrest Carbon Clincher uses a new resin system that builds on Firecrest’s foundation of strength.

Now, add to that our Carbon Clincher technology. Our 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.
