Feel the power of control provided by SonicCore Evolution 120.The hybrid shape of the frame, combined with unique parameters, provides the racket with greater stability, so you can hit cleanly, focused and with great power.Powered by Srixon. The new Sonic Core series is made of Infinergy®, by BASF - a super flexible material that is very light and perfectly fits the requirements of the modern gamer. Infinergy® foam developed by BASF, the world's first E-TPU, has significantly improved rebound properties compared to other materials such as EPP, EVA and EPE. Material bounce tests showed a 46% increase in bounce height compared to the original Sonic Core material. When Infinergy® foam is combined with the Sonic Core frame, the result is greater ball speed off the racket for more aggressive shots.Play with maximum comfort. Sonic Core made of Infinergy® is located in two zones at 2 and 10 o'clock, dampening impact shock and reducing frame vibration by up to 37%, resulting in a more comfortable impact feel and reduced risk of injury.
