Long reed stops added to progressively slow petal tip velocity, for increased petal durabilityReduced frontal area of central wing by 15.6%, combined with a more aerodynamic shapeCombined reed tip area increased by 10.5%, resulting in increased total airflowRubber overmolding on reed tip surface of cage to further enhance petal lifeAirfoil shape added to cage tip to increase air velocity from outer portsAll-new manifold, reed cage and air guide designed for the VForce4RWhen ordering replacement reeds, order one set per reed cageAll-new reed petal resin system, carbon fiber and lay-upPre-curved reed petal ensures better seal at tipWider reed cage for maximum airflowMade in the USA
