Yasaka Rakza Z Extra Hard

Rubber description

Characteristics and Performance

The Rakza Z Extra Hard is a high-performance hybrid rubber characterized by an extremely hard sponge and a tacky topsheet. Designed specifically for aggressive, power-oriented attackers, it requires a high level of physical input and proper, full-stroke technique to fully engage the sponge. It is significantly heavy, which contributes to its stability and power output during loops and counter-drives, though it demands good footwork and high-effort play to avoid “dead” shots into the net.

Playing Dynamics

  • Spin and Touch: The rubber offers exceptional spin generation, particularly on serves, pushes, and opening loops against backspin. The tacky surface provides a high-quality touch in the short game, allowing for precise control and the ability to lift heavy underspin with ease.
  • Speed and Power: While it functions as a controlled, touch-oriented rubber during delicate play, it possesses a notable gear for speed when striking the ball with force. Players can expect a direct, powerful arc that, while initially demanding regarding racket angle, becomes highly rewarding for aggressive topspin play once the stroke is mastered.
  • Suitability: Due to its hardness and weight, this rubber is not recommended for passive or defensive playstyles. It is best suited for experienced players who utilize Chinese-style stroke mechanics and require a durable, tack-integrated solution for the forehand. Consistent maintenance—such as cleaning dust from the surface—is required to preserve the tackiness over the life of the rubber.

Pasé de Rakza Z a Rakza Z EH en el FH (Dr Neubauer Matador Texa), ahora tengo más velocidad, me acostumbré a su dureza y de la paleta después de tres meses, soy más consistente y mejoró la velocidad después del cambio. Hay que limpiarla después de cada práctica para que mantenga lo tacky y preferiblemente cubrirla con el plástico de protección.

I have a friend, my main practice partner, who is probably the biggest fan of this rubber. He used to play J-pen, then turned to a shakehand grip and even tried Chinese penhold for a while, but now is playing J-pen again. But there was something that never changed during all his experiences: RZEH was always there, as his backhand rubber in shakehand and Cpen styles, and now as his J-pen rubber. According to him, RZEH is the rubber that most allows a very closed angle hit with no slippage. Durability is also second to none; with proper care, this rubber can last 18 months. And the topsheet surface is super resistant to cracking; he hit the table many times, and the topsheet remained intact. But there are cons, and the lack of catapult effect might be one if you like a Tenergy-like behavior. Another concern is about the topsheet shining surface; it disappears very quickly and becomes blurry. About performance, it requires a fast and strong swing to produce a fast ball, but when properly hit, the ball goes loaded with spin and is extremely dangerous. It means you must have a good physical condition to play with it; no lazy stroke is accepted with RZEH. It is definitely not for me, although it lasts a long time, which I like. But I do not like the lack of catapult; I prefer a more user-friendly rubber such as Dignics 05. And I do not like at all the blurry topsheet after 3 weeks; this is unacceptable for me.

I use this rubber on my FH with Cybershape Carbon, and I love the tackiness and speed of this rubber. I am a big fan of Yasaka since Mark V. You may feel it is slow at the first 2–3 training sessions, cause the stickiness of the rubber, but you will get a better speed after that (cause the stickiness will reduce to the sweet spot and won’t drop at that point). I was using a boosted H3NEO orange sponge, and I feel like this one is quite similar (without boosting required).
