Right from the start, our objective was to develop a series of top-of-the-line rubbers capable of both speed and spin. Based on this, we developed all of the rubbers in the Rhyzer series with these 2 supporting innovations: 

• Each Rhyzer rubber contains the new JOOLA Powermax sponge with a 2.3mm thickness, which is thicker than conventional rubbers and therefore, generates more speed. 
• The new upper rubber is not only thinner, but also stretched to provide more tension and a better grip. This creates less friction loss, which means more spin. 

In line with our mission of providing all-encompassing products for players of all skill levels, we wanted our line of Rhyzer rubbers to be able to be used by both the average player who needs a softer, more sensitive rubber for more control and the professional player that needs a stiffer sponge for more power. To accomplish this, we created 3 Rhyzer rubbers, each with a different sponge hardness, and 2 types of pimple structures. 

The Rhyzer 43 and Rhyzer 48 are both equipped with thin pimples and a wider distance between each pimple. This allows the ball to penetrate deeper into the rubber surface to create a catapult effect for a higher ball trajectory. At the same time, the softer 43 and 48 degree sponges provide more control. 

In contrast, the Rhyzer Pro 50 has a stiffer 50 degree sponge, thicker pimples, and a narrower distance between each pimple. This means that the ball contact time is shorter, the stroke harder, and the trajectory lower. The Rhyzer Pro 50 rubber plays with maximum power. 

Numerous top players such as Daniel Habesohn, Petrissa Solja and Jörg Rosskopf have contributed to the extensive development of the Rhyzer series. No detail has been overlooked. The JOOLA Rhyzer rubbers is a remarkable series of rubbers suitable for players of all levels.
