JOOLA presents a completely new technically top level rubber series - the new rubbers Rhyzer 48 and Rhyzer 43. They compensate the peculiarity of a plastic ball - low speed and low spin. With two innovative approaches, the improvement of sponge technology and the advancement of pimple geometry, JOOLA is heading towards a total new dimension of rubber development.
The modified flight characteristics of the plastic ball forced many players to correct familiar movement patterns, representing a major challenge that in many cases lead to discontent with the used material. This was the starting point for the development of this completely new rubber series.

The new JOOLA Rhyzer has an extremely thin and grippy surface, being under high tension because of its composition, in combination with the narrow, relatively short pimples and larger gaps, this leads to maximum catapult effect.  In addition the flexible pimples provide an extended dwell time of the ball, sensitive strokes and therefore excellent spin features. Because of the smaller layer thickness of the upper rubber, the JOOLA Rhyzer could be fitted with a thicker sponge in the Maximum version. This „Powermax“ sponge provides an additional dynamics upgrade for the Rhyzer. The large-pored, pink-coloured sponge further intensifies the power and energy potential. Despite high dynamics the large pores still provide sensitive touch and extra control in all playing situations. 

Rhyzer 48 has a 48° sponge and is on the highest level of development when speaking of speed, catapult and spin. It especially suits modern offensive players exasperating their opponents with fast topspin attacks close to the table and from half-distance. Compared to the Rhyzer 43 the topspin trajectory is a little flatter and provides high precision and pressure, especially at offensive actions during the game.
