Wills Wing was the first manufacturer to introduce an affordable aluminum high-performance control bar system: The Slipstream Control Bar. Featuring streamlined aluminum downtubes and interchangeable streamlined basetubes, it enabled pilots to select between aluminum and carbon components based on their performance needs, durability requirements, and budget.

Slipstream aluminum downtubes and basetubes retain a high percentage of the aerodynamic advantage of carbon fiber while offering significantly improved durability and reduced cost. This made high-performance control bars accessible to a much broader range of pilots and applications.
