V Force 4 Reed Valve V-Force All new reed petal resin system, carbon-fiber and lay-up. Pre-curved reed petal ensures better seal at tip. Wider reed cage for maximum airflow. Combined reed tip area increased by 10.5% resulting in increased total air flow. Airfoil shape added to cage tip to increase air velocity from outer ports. Long reed stops added to progressively slow petal tip velocity, for increased petal durability. Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape.
