    The first rubber to be introduced with Yasaka’s Hybrid Energy system was the Rakza 7, which is highly valued by high class players all over the world. The latest addition to the Rakza family is Rakza 9, which has improved speed characteristics. The surface rubber of Rakza 9 has a newly developed formula/rubber combination. In addition the new sponge is made of a more homogenous material and has larger pores. Rakza 9 is the fastest of Yasaka’s Hybrid Energy rubbers and is suitable for technical offensive players, using both high speed and spin to win the point.

    Customer Reviews SummaryAI Summary
    A unique rubber designed with speed priority while maintaining spin performance. It overwhelms opponents with a low arc and straight trajectory, and opinions are divided as a tactical option. Players consistently agree it is back-hand oriented and requires skilled users to unlock its potential.
    ■ Frequently Mentioned Points
    • Low arc with linear trajectory, speed-focused design
    • Exceptional back-drive and counter-attack performance
    • Speed rubber that retains solid spin capability
    • Short lifespan and poor humidity resistance
    • Difficult rubber requiring extended adaptation period
    ■ Representative Voices
    ▲ PositiveExcellent speed output with low trajectory and easy timing shots. Back-drive is nearly unreturnable once it lands, with outstanding close-to-table techniques. A highly distinctive and powerful rubber once mastered.
    ▽ CriticalExtremely short lifespan of only 2-3 months with rapid degradation. Highly sensitive to humidity. Difficult to control; players lacking skill cannot handle it effectively. Some techniques like tsuttsuki become prone to floating.

      It's faster than the other Rakza rubbers! On top of that, the spin doesn't drop off much and the consistency is fine, so it's easy to use. My topspin drives went in solidly whether I was close to the table or a bit further back at mid-distance.

      I figured it would suit the backhand, so I put it there, and I was right. On the forehand it feels harder to control. Performance-wise it's speed-focused like Tenergy 64, but compared to Tenergy 64 the speed still has a way to go. The sponge is about medium hardness.

      I (Experience: 6〜10 years) Numb, for better or worse

      Reviews by user

      For a spin-oriented tension rubber, the ball comes off surprisingly fast. It also has a bit of a grippy feel to it.
      The trajectory is pretty flat, but if you swing through properly you still get spin and the ball drops in on their side.
      Because the ball releases fast, it's great for a hitting style - I'd recommend it if you want your backhand counter to be more of a hit than a loop.
      As for serves, the raw spin isn't that strong, so if you want to really rip your serves, use a more spin-focused tension rubber on the other side.
      About the headline - this is about receiving: because of the above, receiving is easy.
      You can also get a trajectory on chiquita that you just can't get with other spin-oriented tension rubbers.

      It's faster than Rakza 7, and you can put spin on it if you try to, and knuckle balls are easy to do too. I'd recommend it for anyone who wants both speed and spin.

      Yutchi @ cut A real sense of speed!

      Reviews by user

      It's specialized for speed performance. The ball leaving the rubber inevitably feels really quick,, there's not much sense of security either, and the spin isn't amazingly good. I guess you could say it feels like Rakza 7 shifted closer to the X. If your stance isn't solid, you can't control the ball. Compared to the 7, the power went up, and overall it feels a bit harder to use. If you feel the 7 doesn't have enough power, or the X is hard to use, give this one a try!

      God I'm using it on the backhand side

      Reviews by user

      As mentioned in the title, I'm using this on the backhand side.
      The first thing that surprised me was the sponge cells!
      They're pretty large cells.
      The power transfer is a bit lower compared to the X or the 7,
      but personally I find it perfect for consecutive backhand topspin drives.
      Thanks to Hybrid Energy making it easy to control the strength of your shots,
      backhand smashes are stable too.

      If you use this rubber for a long time it ends up getting dented, so I think its lifespan is about 2 to 3 months.
      But while the rubber is still fresh, you can expect really good performance from it.
      It's easier to use on the backhand than on the forehand.
