Donic Bluegrip S1

This hybrid rubber features a blue, 47.5° medium-hard sponge paired with a grippy, slightly tacky topsheet. It is designed to bridge the gap between traditional Chinese tacky rubbers and modern European tensioned rubbers. The construction allows for a high degree of variability, offering a low to medium throw angle that remains relatively linear during play.

Playing Characteristics

• Spin and Control: The rubber excels in the short game, providing high spin potential on serves and pushes. The topsheet is relatively insensitive to incoming spin, which aids in control during passive play. To maximize spin production, players must actively brush the ball to engage the topsheet.
• Speed and Dwell: While the sponge is rated at 47.5°, the rubber feels softer than its density suggests. It possesses a noticeable catapult effect at the “lower high-end,” requiring active strokes to unlock its full power. It is generally less effective for passive blocking compared to non-hybrid ESN rubbers, as it favors offensive, looping-oriented styles.
• Versatility: Due to the hybrid nature of the sponge and surface, it offers multiple “gears” depending on the intensity of the stroke. It is frequently noted as an ideal backhand option, facilitating high-quality loops, flicks, and offensive rallies while maintaining sufficient speed for aggressive play.
