High Aerodynamic Efficiency (H.E.A.)
After many hours in the wind tunnel, we have achieved a design with exceptionally high aerodynamic efficiency (H.E.A.).
The A-7D delivers outstanding performance, generating only 5.9 watts of air resistance at 45km/h, within a wind-angle range between +/- 20 degrees.
It features an ultra-strong 12k carbon construction with internal reinforcement, and a machined aluminum inner Hub equipped with ceramic bearings.
The concave design optimises the wind flow by enhancing the sail effect and increasing the overall speed, ensuring 0 turbulence (drag) as the wind passes unobstructed.
This design also boosts lateral stiffness by 20%.
For 2025, we added a carbon cover with a hook-and-loop fastener to cover the valve and increased its width.
