Volkl Catapult Technology
1. Pre-Load - Activating the Catapult: The Catapult is a spring freely mounted onto the frame and is pre-loaded during the stringing process.
2. Control Phase - Receive Time: As the ball hits the string bed, the Catapult spring compresses and energizes or "loads" the catapult, thus creating a deeper string bed pocket. The increase in receive time (the Control Phase) results in 30% more control and a larger sweetspot.
3. Power Phase - Release Time: The explosive resetting of the Catapult shortens the release time (the Power Phase) by 30%, delivering more power. Power is further enhanced because the ball compresses less and retains more of its own energy.
The dynamic properties of the POWER ARM produce maximum power for every tennis player. Being structurally decoupled from the racquet head, the POWER ARM is pulled backwards upon ball impact. The tennis ball plunges deeper into the stringbed. Right at the moment the ball changes direction, the recoil sets in: The POWER ARM recoils dynamically and leads to extreme acceleration on the ball.
High tech carbon nano tubes combined with cellulose as the base material. Organix material will be loaded up with kinetic energy during ball impact and releases it back again immediately.
