S-4000 WRB
Stiga S-4000 WRB is a 7-ply all-wood offensive blade built for players developing a fast attack and looping game. It features Stiga's WRB technology, which optimizes weight distribution for enhanced power and accuracy. The blend of cedar pine, abachi, kiri, and cotton tree woods creates a distinct, responsive feel that provides a solid foundation for aggressive play while maintaining enough control for strategic shot placement.
The symmetrical 7-ply stack uses cedar pine on the outer layers for hardness and direct feel, with abachi and kiri in the middle for a blend of lightness and flex. The cotton tree core adds stability. This specific sequence is engineered to balance speed from the stiff outer plies with the control and feedback inherent in the wood composition.

✦Our expert analysis of this blade's performance characteristics
This blade is built for pace, earning a high speed rating ideal for fast attacks and finishing points quickly. The stiff 7-ply wood construction and forward weight balance from the WRB system work together to generate impressive ball speed, allowing players to put significant pressure on opponents.
While emphasizing power, the S-4000 WRB maintains respectable control. This balance allows for effective shot placement and strategic play, making it manageable for players developing their offensive game who still need to accurately direct their loops and drives.
You get a direct and crisp feedback on contact. The 7-ply construction with woods like cedar pine creates a medium-hard feel that communicates the ball's impact clearly, aiding in precise shot execution for drives and loops.
The blade tends to produce a medium-high throw angle, which is beneficial for offensive play. This helps in lifting the ball with good arc and spin over the net, especially during looping rallies from mid-distance.
The all-wood build offers a moderate dwell time. It provides enough grip on the ball for effective spin generation during loops, while remaining responsive enough for quick counter-attacks and fast exchanges at the table.
This is a stiff blade. The rigidity is a defining characteristic that contributes directly to its speed and direct, catapult-like feel, making it particularly effective for powerful, penetrating strokes.
Players can expect a medium level of vibration. The WRB system helps manage the feedback, but as a wood blade, it transmits a clear, tangible sensation through the handle, giving players informative touch on their shots.
As a Stiga product, this blade benefits from the brand's established reputation for quality woodcraft. The construction is durable and consistent, offering reliable performance that holds up well for training and match play, representing good value in its category.
Technology
The core technology is the Stiga WRB (Weight Balance Improved) system. This involves hollowing sections of the handle to reduce weight and strategically shift the blade's balance point towards the head. The result is increased hitting power, improved accuracy, and faster racket recovery. Combined with a 7-ply all-wood construction of cedar pine, abachi, kiri, and cotton tree, it creates a blade optimized for a blend of speed and control in offensive play.
