The VÖSTRA 1 Power Arm is unique with the Power Arm located in the throat of the racquet. The German-engineered Power Arm gives the VÖSTRA 1 Power Arm a very smooth and controllable power by allowing the string bed more movement than a traditional throat design which aids in ball cupping for better control. The Power Arm’s movement also absorbs more vibration making the racquet extremely comfort-able to use.
