*Joola Rhyzm P has an in-built GeoGrip-Power-Technology which develops significantly more grip of the ball for more spin due to an intense friction surface structure. Find out for yourself, use the P’s in your game and become even more successful! RHYZM – on the market for 2 years and already nearly a classic! The focus fell on development and improvement of the sponge up until now, whereas here a much improved rubber surface has been precisely worked upon. This has leaded to the rubber having substantially more grip, with which not only more spin can be generated, but also better control and the durability is improved. Ideal also for use with the new Poly-ball.
