Zipp’s 808 Firecrest® Tubeless rim-brake wheel makes you faster with an 82mm rim depth that’s fast, stable in crosswinds, and now tubeless ready. That means you get all the aero benefits with having the ability to run lower tire pressure for increased cornering grip and compliance and reduced rolling resistance, without the risk of pinch flats. This wheelset is infused with technologies developed in our Indianapolis advanced development lab. Zipp’s ABLC™ Sawtooth™ Technology uses a complex dimpling pattern to improve aero efficiency. Zipp’s ShowStopper™ textured braking surface delivers unrivaled rim braking performance in wet or dry conditions. At the center of the 808 Firecrest Tubeless rim-brake is a versatile and durable new hubset, the German-engineered ZR1. Zipp’s new wheel cosmetics make this wheelset a perfect pairing of speed and style.
In developing the original 303 wheels, Zipp discovered that a wider rim increases lateral stiffness for sprinting and cornering while also providing greater vertical compliance for greater control, comfort and durability. That wider rim profile led ZIPP to develop our Firecrest technology, which revolutionized aerodynamic efficiency and stability for carbon wheels. The proprietary Firecrest rim shape optimizes the aerodynamic profile of the front half and - here's the revolutionary part - the back half of the wheel. Firecrest moves the wheel's center of pressure to be more in line with the steering axis for stability in even the stiffest crosswinds. All of that innovation along with the precision control of disc braking gives you a wheel that's as smooth as it is tough.
The industry leading silicon carbide Showstopper brake track continues to evolve and improve, providing unmatched stopping power and modulation regardless of weather conditions or the length of the descent.
Zipp’s Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
ZR1 DB hub is engineered in Germany with better seal design for improved durability and quicker response with 66 points of engagement.
