Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

The revised ABLC® (Aerodynamic Boundary Layer Control) design reduces air resistance through more and smaller turbulences in order to ensure unsurpassed stability and control even in the strongest winds.

Zipp`s exclusive Firecrest® rim has rewritten the history of wheel development. The result was improved aerodynamics, ride quality, wheel strength and stability even in extreme cross winds. As a result, the entire Firecrest wheel family - from the 202 to the 808 Firecrest - is better and more versatile than ever and is also equipped with the new 77/177 hub set.

The Firecrest technology, starting with rims with almost constant height up to the spoke bed, offers the first aero profile that effectively regulates the airflow in the rear half of the wheel. By moving the center of gravity - the center of the forces acting laterally on the rim - close to the steering axis, Firecrest offers stable, reliable handling in any wind angle. As Zipp found on their 303, a wider rim like Firecrest wheels increases lateral stiffness for optimal sprints and cornering, while also providing greater vertical compliance for more control, comfort and resilience on rough surfaces.
