A shape designed by reason.
Allocating pimples with smaller diameter densely—this is the answer obtained by accumulating research results.
The special pimple shape results in a top sheet which does not easily yield to the opponent’s attack. By combining this newly developed top sheet with Spring Sponge, increased power and sense of holding, a feature of the Tenergy series, are achieved. Tenergy 19 gives a high performance not only for active but also for passive shots against strong returns.
Now, it’s in your hand to realize your full potential with Tenergy 19.

Densely allocated pimples with a smaller diameter:
Code no. 219’s pimple shape1), used in Tenergy 19, features 1.5 mm pimples which are slightly thinner than other Tenergy series’ and are allocated as densely as the rule allows. The shape is chosen from “the shapes that enhance the rubber’s spin and speed performance” which Butterfly patented2).
1) A pimple shape consists of multiple elements such as its diameter, height, or distance between pimples
2) Patented in Japan (No. 6738472)
Thin pimples to unite the powers
Numerous tests have demonstrated that the Tenergy 19 using the no. 219 pimple shape, exhibits high spin and speed performance, especially when hit hard.
Why does this shape enhance the performance of the rubber? Let’s have a closer look, focusing on the moment when the ball digs into the rubber and bounces back.
Ball digging into sponge
Thin pimples such as no. 219 depress and flatten more easily. Therefore, when the ball hits the rubber, the ball does not slip on the rubber but digs into it. The rubber “holds” the ball in place.
Ball bouncing back
The power pushing the ball back against the rubber is generated by each pimple in contact with the sponge. In the case of No. 219, which has thinner pimples, though the power that each pimple pushes back is small, the number of pimples that push the ball back increases because the pimples are densely allocated. As a result, the more power is united, and thus it does not easily yield to the opponent’s strong shots.
Combination with Spring Sponge creates a grippy rubber
Spring Sponge, introduced in 2008, is revolutionary in terms of successfully combining flexibility and high elasticity, and the crucial technology responsible for bringing high performance to the Tenergy series.
We managed to enhance the touch of “holding the ball” more by combining Spring Sponge and the top sheet with development code no. 219’s pimple shape. Since the ball is more likely to fly in the direction of racket swing, it demonstrates its strength most when playing counter topspin or banana flicks.
Performance comparison with Tenergy 05
The ball flies in the direction of racket swing
The ball flies easily in the direction of racket swing as the top sheet with the no. 219’s pimple shape grips the ball well. The ball flies with a more curved trajectory than Tenergy 05, and making it easier to land deeper in the opponent’s court compared to when hitting with 05.

Power increased by 0.8%
Tenergy 19’s top sheet, where a ball will not slip on the rubber nor easily yield to the opponent’s strong shots leads to high performance in spin and speed when playing a fast shot and provides increased power1).

Improved ease of power topspin, counter topspin and short plays.
The unique top sheet makes it easier to play powerful topspins. Furthermore, thanks to improvement of the grip, the rubber becomes more suited for a banana flick and counter topspin.

* Results are similar, regardless of the thickness of the sponge.
Nearly the same weight with 05
Tenergy 19 is almost the same weight as Tenergy 05 and is lighter than Tenergy 05 Hard. “19” would be a good option for players seeking a faster swing speed through reduced total weight of the racket.
