Butterfly Roundell Hard – High Tension Rubber for Aggressive Control
Butterfly Roundell Hard is a high-tension, pimples-in table tennis rubber designed for players seeking to combine speed, spin, and exceptional control. With a soft topsheet, harder sponge, and High Tension technology, Roundell Hard delivers powerful offensive shots, short serves and pushes, and stability during delicate close-to-the-table play. Made in Japan and ITTF-approved, this rubber is an ideal choice for beginner to intermediate attackers looking for aggressive play with high control—especially with 40+ plastic balls.

Key Features:
• Rubber type: High Tension, pimples-in
• Speed: 78/100
• Spin: 49/100
• Trajectory: 62/100
• Sponge hardness: 40° (hard)
• Sponge thicknesses: 1.7 mm, 1.9 mm, 2.1 mm
• Colors: Red, Black
• Origin: Japan
• Approval: ITTF-approved

Advanced Construction for Modern Offensive Play:
• Sponge (40°): The harder 40° sponge (Butterfly scale, approx. 45–50° on ESN scale) is dense and elastic, providing more power on attacks and shorter trajectories for serves and pushes. Compared to the original Roundell (35°), the Roundell Hard sponge is firmer, ideal for players with faster strokes. It offers a stronger catapult effect and lower rebound angle for easier control of short strokes. Stability is maintained when blocking and counter-attacking.
• Soft Topsheet: The topsheet is soft and flexible, optimized for spin and speed. It increases dwell time, allowing strong topspin generation and controlled trajectories. Durable and wear-resistant, it's adapted for plastic balls, maintaining consistent grip. Compared to Bryce Speed, Roundell Hard offers more spin—closer to Tenergy 05—but with a more manageable speed, suitable for beginners.
• Pimple Geometry: The medium-length, densely spaced inward pimples are optimized for speed (78/100), spin (49/100), and trajectory (62/100). This structure supports easy execution of topspin loops, short pushes, flicks, and blocks while maintaining high control. Compared to Roundell, Roundell Hard combines this geometry with a harder sponge, producing sharper, shorter strokes suited to aggressive attackers.
• High Tension Technology: Roundell Hard uses High Tension technology to stretch the topsheet, increasing elasticity and speed. This enhances the catapult effect, boosts pimple reactivity, and enables fast attacks and spin generation. Compared to Tenergy 05, the High Tension effect here is milder, prioritizing consistency and control, making it more manageable for beginner and intermediate players.

Offered in 1.7 mm, 1.9 mm, and 2.1 mm sponge thicknesses:
– 1.7 mm for controlled strokes and backhand play
– 1.9 mm for balanced performance
– 2.1 mm for maximum speed and spin on the forehand
The rubber has a medium weight (uncut ~65 g, cut ~45–50 g), comparable to Sriver G3 or Yasaka Rakza 7. Available in red and black, complying with ITTF standards. Butterfly recommends using Free Chack glue when assembling the rubber.

Technical Profile Optimized for Controlled Offense:
• Speed: 78/100 – Fast, suitable for topspin loops, flat hits, and counterattacks. Slightly slower than Bryce Speed (~80/100), but close to Tenergy 05 in consistency and controlled power.
• Spin: 49/100 – Strong spin generation in loops, serves, and flicks. More spin than Bryce Speed and original Roundell (43/100). Less than Tenergy 05 (~60/100), but sufficient for looping and disruptive play.
• Control: While not explicitly rated, the soft topsheet and harder sponge provide high control, especially in blocks, short pushes, and serves. Compared to Roundell (control ~8/10), Roundell Hard is slightly less forgiving due to the firmer sponge but well-suited for players with fast strokes.
• Trajectory: Medium-high, slightly arcing (arc: 62/100), suitable for topspin looping and controlled play. Higher than Roundell for net safety, yet shorter due to the harder sponge, aiding control in short serves and pushes. Users highlight the rubber’s “control,” “power,” and “precision in short strokes,” especially during looping.

Versatile Compatibility with Various Blades:
• Butterfly Kong Linghui: Offers feel and control for developing technique.
• Butterfly Boll Offensive: Balances speed and control—ideal for aggressive shots.
• Butterfly Gionis Carbon Offensive: Maximizes speed—great for looping.
• Butterfly Primorac: Adds stability—suitable for all-round shots.
• Butterfly Innerforce Layer ZLF: Adds flexibility—perfect for topspin looping.

Also compatible with hard blades like Yasaka Ma Lin Extra Offensive, where the soft topsheet and firm sponge offset blade hardness to provide better spin and control. Users recommend using Roundell Hard on the forehand with 2.1 mm sponge for maximum power and spin, or on the backhand with 1.9 mm for improved blocking control. The rubber is optimized for plastic balls—its flexible topsheet effectively generates spin and speed.

Designed for Offensive Players Seeking Speed, Spin, and Consistency:
• Ideal for beginner attackers developing topspin loops and fast close-to-table play
• Great for intermediate players wanting a rubber suited for power shots and short pushes
• Best near the table: Topspin loops, flicks, short serves, and pushes
• Offensive strokes: Counterattacks, flat hits, heavy spin shots
• Serving and receive: Enables short, disruptive side-spin serves and precise receives

The rubber performs exceptionally in topspin loops (8.8/10) thanks to strong spin and stable trajectory. In short pushes and serves (8.6/10), it provides accuracy and control, especially due to the harder sponge. During blocks (8.4/10), it offers stability against topspins. In flicks and short play (8.3/10), it enables quick responses. Compared to Roundell, Roundell Hard is more aggressive—ideal for players with faster strokes. Users praise its “power,” “control,” and “short-stroke precision,” particularly on the forehand.

Butterfly Roundell Hard stands out as a dynamic offensive rubber:
• Speed (78/100): Suited for topspin loops and counterattacks
• Spin (49/100): Effective in loops and serves
• Control: High—ensures stability in attacks
• High Tension Technology: Catapult effect, enhanced speed
• Harder Sponge: Shorter trajectories, sharper strokes
• Japanese Quality: ITTF-approved, made in Japan
