The Aero Force has a mid-range tension of 19-21 lbs allowing for more rebound and power, perfect for the mid-range player. Nylon creates a strong and durable string with little chance of moisture absorption. The alloy creates strength and durability whilst the graphite shaft keeps the weight down. At 905g this weight provides more speed and momentum to the shuttle. The polyurethane grip provides great cushioning whilst also resisting sweat and vibration. Suitable for all Badminton players.
