With the sponge thickness ultramax, RASANTER enters new dimensions. With a thickness of 2.3 mm the sponge is the thickest modern TENSOR sponge so far, made in Germany. By minimizing the entire circumference of the surface rubber, additional volume is provided and paves the way for huge rebound power. This is the ultimate answer to the loss of speed by the 40+ ball!
In addition to a newly developed sponge, RASANTER is also based on a surface specially designed for the 40+ ball. The new, shriveled pimple geometry provides the sponge more space to unfold its strengths. In addition, it expands the contact surface to the ball at the ball hitting momentum and enables more rotation in general.
