JOOLA Tronix ZGR is a professional-grade offensive inverted table tennis rubber designed for players seeking maximum spin, power, and precision in aggressive gameplay.
ITTF-approved, this rubber features a hard “Balance” sponge (~56° ESN scale, cream-colored) and a highly grippy “Hyper Traction” topsheet, offering extremely high spin (134/200, ~12.5/20), controlled speed (118/200, ~11.5/20), and excellent control (112/200, ~15/20). The innovative pimple structure (height 0.9 mm, width 1.6 mm, spacing 0.8 mm) creates a medium-high arc trajectory (7/10), making topspin strokes easier and ensuring shot precision. Optimized for the plastic 40+ ball, Tronix ZGR provides direct energy transfer, exceptional spin, and stable handling against incoming attacks, making it an ideal choice for advanced players emphasizing offensive play at the table or mid-distance. Thanks to its lightweight (~44 g cut) and durability, JOOLA Tronix ZGR is a top-tier option reflecting JOOLA Professional Line technologies used in elite-level competition.

JOOLA Tronix ZGR Features a Modern Construction That Combines a Hard Balance Sponge and Ultra-Grippy Hyper Traction Topsheet, Ensuring Maximum Spin, Power Transfer, and Control:

Sponge (~56°):

The hard “Balance” sponge (~56° ESN scale, cream color) is designed for direct energy transfer and explosive dynamics. Compared to JOOLA Tronix ACC (~47.5°, 124/200 speed), Tronix ZGR has a harder sponge, offering less speed (118/200) but more spin (134/200) and stable control (112/200). Compared to JOOLA Dynaryz ZGR (~50°, 130/200 spin), Tronix ZGR is harder, delivering higher spin and a more direct feel. Versus Butterfly Dignics 05 (~40°), the sponge is harder, with shorter dwell time but greater power and spin for aggressive topspin play.

Topsheet:

The ultra-grippy “Hyper Traction” topsheet (134/200 spin) is elastic, with short and wide pimples optimized for the plastic 40+ ball. It ensures maximum ball grip, especially during topspins, serves, banana flicks, and counterattacks. Compared to JOOLA Dynaryz ZGR (130/200 spin), Tronix ZGR is grippier, offering more spin and direct energy transfer. Compared to Tibhar Evolution MX-P, Tronix ZGR is grippier but requires more precise technique.

Hyper Traction Technology:

The extremely grippy topsheet enhances friction and ball contact, delivering maximum spin (134/200) and precision (8.5/10). The pimple structure (0.9 mm height, 0.8 mm spacing) creates a medium-high arc trajectory (7/10), ideal for topspins and counterattacks. The topsheet grips the ball firmly, ensuring high spin even during soft shots.

Balance Technology:

The hard sponge (~56°) enables stable power transfer, allowing dominance in topspin-to-topspin rallies and effective responses to incoming attacks. Compared to JOOLA Tronix CMD (~42.5°, 115/200 speed), Tronix ZGR is faster and grippier, yet maintains high control (112/200), making it suitable for aggressive attackers seeking spin and accuracy.

Weight and Durability:

JOOLA Tronix ZGR is lightweight (~44 g cut), similar to JOOLA Tronix ACC (~43 g) and lighter than JOOLA Dynaryz AGR (~49.37 g). This lightness allows pairing with heavier blades like the Butterfly Zhang Jike Super ZLC without losing balance. The rubber is durable, retaining its grip and elasticity properties even after intensive use, making it a cost-effective choice.

The rubber is offered in 2.0 mm and Max thickness, suitable for offensive play, ensuring maximum spin, power transfer, and control. Colors – red and black – meet ITTF standards. It is recommended to use water-based glues such as JOOLA Lex Glue for mounting.

Technical Ratings and Play Characteristics:

Speed (118/200, ~11.5/20):

JOOLA Tronix ZGR offers controlled speed, suitable for topspin attacks, flat hits, and counterattacks. Compared to JOOLA Tronix ACC (124/200), its speed is slightly lower, but it provides more spin and stability. Compared to Butterfly Dignics 05 (~13/20), the speed is a bit lower, but Tronix ZGR is grippier and more precise.

Spin (134/200, ~12.5/20):

Thanks to the ultra-grippy “Hyper Traction” topsheet, the rubber produces very high spin, especially in topspins, serves, and banana flicks. Compared to JOOLA Dynaryz ZGR (130/200), Tronix ZGR offers more spin, close to Japanese rubbers like Butterfly Dignics 05 (~13/20). The medium-high arc (7/10) supports topspins over backspin balls, creating a "kick" effect after the bounce.

Control (112/200, ~15/20):

The hard sponge (~56°) and grippy topsheet ensure excellent control, particularly in topspin shots and while handling incoming attacks. Compared to JOOLA Tronix ACC (92/200), Tronix ZGR offers more control, making it more forgiving. Compared to Tibhar Evolution MX-P, Tronix ZGR is grippier but demands more precise technique.

Trajectory (7/10):

The medium-high arc trajectory in topspin strokes is ideal for fast attacks and counterattacks at the table or mid-distance. When blocking, the trajectory is straighter, suitable for stable blocks against aggressive shots. Compared to JOOLA Tronix CMD (~8.5/10), Tronix ZGR’s trajectory is slightly lower but still aids in topspin execution.

Precision (8.5/10):

High precision allows players to direct the ball to targeted areas, especially during topspins and counterattacks.

Playing Aspects:

Driving (Attacks): 9.5/10 –

JOOLA Tronix ZGR excels in topspin attacks, especially on the forehand side, producing powerful shots with maximum spin. Ideal for third-ball attacks and counterattacks on backspin balls, especially at the table or mid-distance.

Blocking: 9.3/10 –

Blocks against topspin are stable and precise due to the grippy topsheet and hard sponge, offering a strong response to incoming attacks.

Pushes (pushing): 9.4/10 – Tronix ZGR performs well in short pushes, keeping the ball low and controlled thanks to the tacky top sheet and hard sponge. The rubber enables excellent spin variation and control in short game play.

Loops (topspin): 9.7/10 – Designed for powerful topspin strokes, especially against backspin. The rubber produces high amounts of spin and a medium-high arc, which ensures consistency and pressure in topspin rallies. Ideal for loopers playing close to the table or mid-distance.

Counterloops: 9.6/10 – Tronix ZGR excels in counterlooping rallies due to its high grip and direct energy transfer. The hard sponge allows confident re-looping against heavy topspin, while maintaining precision and spin.

Flicks: 9.3/10 – The tacky surface aids in banana flicks and short flicks over the table, grabbing the ball well even in tight angles. Perfect for aggressive returns on short serves.

Serving: 9.2/10 – The high grip of the Hyper Traction surface allows generating spinny and deceptive serves. Excellent for side-spin, backspin, and no-spin variations with high precision.

Chops: 8.2/10 – While not designed for heavy defensive chopping, the rubber still allows controlled backspin returns, especially with good technique. Suitable for mixed offensive-defensive styles.

Durability: 9.5/10 – Tronix ZGR maintains its tackiness and elasticity over time, even with regular use. The rubber's lifespan is excellent compared to many other high-performance offensive rubbers.

Final Verdict
JOOLA Tronix ZGR is a high-end offensive rubber designed for advanced players who emphasize heavy spin, direct power, and precision. With its hard Balance sponge and grippy Hyper Traction surface, it delivers explosive topspins, reliable counterattacks, and confident control in both close and mid-distance play. While it may require refined technique due to its hardness, it rewards skilled players with world-class performance.
