Butterfly Tenergy 05 (Tensor)
This is the first rubber to feature Butterfly’s 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 surface grip.
The result is a rubber that produces massive amounts of spin on serves and topspin drives. Tenergy is also the fastest most explosive rubber in our line all without the use of any speed-glues or tuning. Tenergy will keep its speed throughout the life of the rubber without need for any special treatments. Finally a rubber that will make you feel like you are playing in the days of the 38 mm ball again!
