High elastic sponge, large deformation of sponge, fast recovery, stable and fast arc, suitable for arc.
Viscose sur, easy to control, high friction, good rotation performance and strong stability.
The new stepped particle structure and bottom reinforcement ensure longevity and attack speed.
While ensuring high elasticity, the covering force and supporting force of the ruer sleeve are optimized, the rotation of the ball is enhanced, and the endurance of force is greater.
Suitable for hard floors, easy to use, high fault tolerance, suitable for beginners.

Features:
This is the first ruer to feature Butterflys new "Spring Sponge". Spring Sponge feels hard yet its new technology allows it to hold the ball on the racket longer. Tenergy 05 combines this new explosive sponge with a new tensioned top-sheet with maximum sur grip.
The result is a ruer that produces massive amounts of spin on serves and topspin drives. Tenergy is also the fastest most explosive ruer in our line all without the use of any speed-glues or tuning. Tenergy will keep its speed throughout the life of the ruer without need for any special treatments.
