Densely allocated pimples, code No.219, with the pursuit of speed and spin, realised a top sheet which does not easily yield to the opponent’s attack. Combining this newly developed top sheet with Spring Sponge, the increased sense of holding, a feature of the Tenergy series, is achieved; this is highlighted when the ball is hit strongly and precisely. Tenergy 19 gives a high performance not only for active strokes but also passive strokes against strong returns.
