CeramicSpeed OSPW Aero System Description:

CeramicSpeed's OSPW Aero system has been developed in close collaboration with one of the world's leading aerodynamicists. The development process behind the OSPW Aero spanned over two years, where extensive wind tunnel testing influenced multiple design iterations. The end result is an entirely new cage structure wrapped around our existing mechanically optimized design.
