- 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
- Combined reed tip area increased by 10.5%, resulting in increased total airflow
- Rubber overmolding on reed tip surface of cage to further enhance petal life
- Airfoil shape added to cage tip to increase air velocity from outer ports
- All-new manifold, reed cage and air guide designed for the VForce4R
- When ordering replacement reeds, order one set per reed cage
- 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
