New FFWD Technology - Darc™

14 May 2009

New proprietary aero technology

makes F9R the ultimate

speed wheel.


The new and revolutionary Darc™

profile improves aerodynamics



Air has the charateristic to stick to its

surface. By creating a negative arc

section the air will be compressed

more at the positive section. This will

increase the pressure just like on the

topside of an airfoil. Increased pressure results in a faster airflow and

less resistance on the wheel, giving you more speed at the same effort.

And that’s what it’s all about with high speed wheels.


Darc™ is also available on the F6R/C.
