It takes true engineering knowledge to optimise wheels to work with precision and control at the rim height of the 808 Firecrest. While the wheels prove their aerodynamics and controllability every weekend in road races, triathlons and time trials around the world, you can only understand how incredibly good they really are by riding them. As a set they’re faster than any other.
The revised ABLC (Aerodynamic Boundary Layer Control) design reduces drag through more and less turbulence to ensure unsurpassed stability and control even in the strongest winds. Flow separation
Firecrest technology - from wheels with almost constant height to the spoke bed - offers the first aero profile that effectively regulates the airflow in the rear half of the wheel.
Centre of pressure
By shifting the centre of pressure (the centre of the lateral forces acting on the rim) close to the steering axle, Firecrest offers stable, reliable handling at any wind angle.
As the Zipp 303 has shown, a wider rim increases lateral stiffness for optimum sprinting and cornering. It also offers greater vertical flexibility for more control, comfort and resistance on rough surfaces.
