The observation of nature compels us the perfect copy of it. Parabolic shape of thrust shaft torsional forces, as with the fish looking for the maximum thrust with minimum effort and resistance.
The rear spoiler does work throughout the blade and not just as happens in other blades, making his final parabolic work between 15/20 cm, allowing a stronger push and translated in energy. This now joined the new T700 and the new Carbon Vgr profile.
Serve with profile mounting adapter.
Including bag when bought Spetton shoes too.
