Sauer & Tröger Secret Flow Chop is a high-quality table tennis rubber with inward pimples (pimples in), designed for defensive and all-round players seeking maximum spin, control, and disruption effect, especially when playing with the 40+ plastic ball. ITTF approved, this rubber’s soft top sheet combined with a medium-hardness orange SC sponge (~45° on the ESN scale, estimated Soft+ characteristic) ensures balanced speed (84/100, ~10.3/20), exceptional spin (100+/100, ~10.5/20), and excellent control (97/100, ~12.5/20). The special synthetic top sheet with high grip and the unique SC sponge create a strong disruption effect (100/100, ~10/10), allowing dangerous topspin shots, precise blocks, and effective defensive strokes. Optimized for pimple players, especially those using long pimples on the backhand, Secret Flow Chop offers the ideal balance between offense and defense, making it a great choice for players looking for spin and control. Due to its light weight (~43 g trimmed) and durability, Sauer & Tröger Secret Flow Chop is a premium choice suitable for high-level competition.

Rubber Description and Performance:

Sauer & Tröger Secret Flow Chop stands out with its innovative construction, combining a soft, grippy top sheet with a medium-hardness orange SC sponge, ensuring maximum spin, control, and disruption effect:

• Sponge (~45°): The medium-hard orange SC sponge (~45° ESN scale) provides balanced speed (84/100) and excellent control (97/100), allowing precise ball handling on topspin, blocks, and defensive strokes. Compared to Sauer & Tröger Zargus (85/100 speed, 97/100 control), Secret Flow Chop is slightly slower but offers more spin (100+/100) and stronger disruption effect (100/100). Compared to JOOLA Rhyzen ZGR (~45°, 120/200 speed), Secret Flow Chop’s sponge is slower but provides more control and spin. Compared to Yasaka Mark V (~45°), Secret Flow Chop offers similar control but stronger spin and disruption effect.

• Top sheet: The soft, grippy synthetic top sheet with visible pores delivers outstanding spin (100+/100) and strong disruption effect (100/100). The sheet is pre-tensioned, so it may expand slightly after unpacking, increasing grip and spin potential. Compared to Sauer & Tröger Hipster (80/100 spin), Secret Flow Chop offers significantly more spin and stronger disruption. Compared to Butterfly Tenergy 05, Secret Flow Chop is slower but more controllable and better suited for defensive play.

• Pimple structure: The inward pimples combined with the soft, grippy top sheet generate maximum spin, especially on topspin shots against backspin balls, while providing high control during blocking or defensive strokes. The top sheet reduces the effect of incoming spin, making it suitable for players using long pimples on the backhand. Compared to Sauer & Tröger Zargus (short pimples), Secret Flow Chop offers more spin and forgiveness.

• Weight and durability: Sauer & Tröger Secret Flow Chop is lightweight (~43 g trimmed), similar to JOOLA Rhyzen ZGR (~43 g) and lighter than Butterfly Tenergy 05 (~47 g). This lightness allows pairing the rubber with heavier blades like Butterfly Innerforce Layer ALC without losing racket balance. The rubber is durable, maintaining grip and elasticity even after intense use, making it economical.

• The rubber is offered in 1.5 mm, 1.8 mm, and 2.1 mm thicknesses, allowing a choice between maximum control (1.5 and 1.8 mm) and more power (2.1 mm). Colors – red and black – comply with ITTF standards. Recommended to use water-based glues like Sauer & Tröger Glue or JOOLA Lex Glue for mounting.

Technical Ratings and Gameplay Characteristics:

• Speed (84/100, ~10.3/20): Medium-speed rubber, suitable for topspin strokes, pressure pushes, blocks, and defensive strokes close to or away from the table. Compared to Sauer & Tröger Zargus (85/100 speed), Secret Flow Chop is slightly slower but offers more spin and disruption effect. Compared to Butterfly Tenergy 05 (~13/20 speed), it is slower but offers more control.

• Spin (100+/100, ~10.5/20): The grippy top sheet generates exceptional spin, especially on topspin shots against backspin balls, creating a dangerous disruption effect (100/100). Compared to Sauer & Tröger Hipster (80/100), spin is significantly higher. Compared to JOOLA Rhyzen ZGR (~10/20), Secret Flow Chop offers similar spin but stronger disruption.

• Control (97/100, ~12.5/20): The medium-hard SC sponge (~45°) and soft top sheet ensure excellent control, especially on blocks, topspin, and defensive strokes. Compared to Sauer & Tröger Zargus (97/100), control is similar but Secret Flow Chop offers more spin and forgiveness. Compared to Butterfly Tenergy 05 (~10/20), control is higher, making it suitable for defensive players.

• Disruption factor (100/100, ~10/10): The rubber generates a very strong disruption effect, especially on topspin and blocks, creating dangerous spin that disrupts opponents. Compared to Sauer & Tröger Hipster (89/100), Secret Flow Chop’s disruption effect is stronger, especially against backspin balls.

• Trajectory (8.0/10): Medium arc trajectory, suitable for topspin, blocks, and defensive strokes. Compared to Sauer & Tröger Zargus (7.5/10), trajectory is slightly higher, facilitating topspin strokes. On blocking, the trajectory is stable, suitable for effective blocks against topspin shots.

• Precision (9.2/10): High precision allows players to place the ball accurately, especially on topspin, blocks, and pressure pushes.

Gameplay Aspects:

• Topspin shots: 9.7/10 – Highly effective topspin rubber, especially on backspin balls, generating dangerous spin and disruption effect.

• Blocking: 9.5/10 – Effective for blocking topspin shots near the table, absorbing spin and ensuring stability and precision.

• Pressure pushes: 9.4/10 – Allows aggressive pushes on backspin or no-spin balls, generating strong spin and disruption.

• Defensive strokes (chopping): 9.6/10 – Effective for defensive shots near or away from the table, generating strong backspin and accurate trajectory.

• Counterattacking: 9.0/10 – Suitable for counterattacks near the table, especially on no-spin or backspin balls, generating precise shots.

• Serving and receiving: 9.3/10 – Serves generate strong spin, especially side spin, suitable for disruptive play. Passive receiving (9.5/10) is stable due to reduced spin effect, active receiving (9.1/10) is effective due to spin and control.

• Flick shots: 9.2/10 – Banana flicks are effective thanks to the grippy top sheet facilitating topspin on backspin balls.

Compatibility with blades:

Sauer & Tröger Secret Flow Chop is suitable for various blades, especially those emphasizing control, spin, and defensive play:

• Sauer & Tröger Hellfire: Maximizes control and disruption effect, suitable for technical defenders.

• Butterfly Hadraw Shield: Provides control, suitable for defensive strokes and topspin strokes.

• Nittaku Barwell Fleet: Provides feel, suitable for topspin strokes and pressing pushes.

• Yasaka Sweden Defensive: Balances control and spin, suitable for defensive play.

• Donic Defplay Senso: Provides additional control, suitable for precise blocks.

Due to its light weight (~43 g trimmed), Sauer & Tröger Secret Flow Chop pairs perfectly with heavier blades such as Butterfly Defensive Pro or Stiga Defensive Classic without losing racket balance. Users recommend using this rubber on the forehand side with 1.5 mm or 1.8 mm sponge thickness for classic defenders aiming for maximum control, or 2.1 mm sponge for modern defenders seeking attacking options.
