Yasaka Rakza 7 Review: The Value Tensor With Near-Tenergy Spin

By UltraSpin · 2026-06-06 · rubber

Pros

  • Huge grip and spin from the natural-rubber topsheet — reviewers put it close to Tenergy 05
  • Outstanding control and consistency, especially in the short game, blocks and pushes, with no runaway Tenergy catapult on touch
  • Excellent value and durability — a long-time club favourite with strong cost-performance
  • Versatile on both wings, and offered in 1.8 / 2.0 / max to tune speed against control
  • Lighter than tacky Chinese rubbers, with an ideal medium throw angle

Cons

  • Speed is moderate, around 80 percent of top rubbers — you supply pace with placement and stroke
  • Max thickness can feel too fast for a control game; many prefer 1.8 or 2.0 for touch
  • Reacts to incoming spin, so control play and clean technique matter, and it needs regular cleaning for longevity

Few rubbers are recommended as often at club level as the Yasaka Rakza 7. It is a Hybrid Energy tensor that pairs a high-natural-rubber, grippy topsheet with a medium-hard Power Sponge, and it has built a reputation as the value benchmark: most of the spin of the premium rubbers, with control and durability that keep players coming back season after season.

Performance

Spin is the headline. The natural-gum topsheet grips hard, and reviewers repeatedly put the spin close to Tenergy 05 on loops, serves and opening balls against backspin. What sets it apart is control: blocks, pushes and the short game are exceptionally consistent, with none of the runaway catapult that makes premium tensors twitchy on touch, so much so that opponents sometimes ask if it is anti-spin. The trade-off is speed, around 80 percent of top rubbers, so you place and spin rather than blast, and the medium throw angle suits both wings, especially the backhand. Thickness lets you tune the balance, with 1.8 and 2.0 favouring control and max adding pace. It is light for its grip and durable, provided you clean it, and it reacts only moderately to incoming spin so a sound stroke keeps it predictable.

What Reviewers Agree (and Disagree) On

Reviewers agree strongly on spin, control, consistency, durability and value, and many name it their favourite backhand rubber. The disagreements are about speed and longevity: some want more top-end pace (and find max too fast for control), and a few report the grip fading without regular cleaning.

Who Should Buy It

Buy it if you are a developing to advanced offensive player who wants a controllable, very spinny tensor with excellent value, on either wing and especially the backhand. It is a superb first real tensor. It is less ideal if you want explosive, top-end speed straight from the rubber.

FAQ

Is the Rakza 7 as spinny as Tenergy 05?

Very close on loops and serves, according to most reviewers, at a fraction of the price, though Tenergy 05 still has a higher throw and more catapult.

Which thickness should I choose?

1.8mm or 2.0mm for the most control close to the table; max if your game is faster or further back and you want more pace.

Is it good for the backhand?

Yes — it is one of the most recommended backhand rubbers at club level, thanks to its control, blocking and spin.
