Spring Sponge X - Gray
The Spring Sponge X in the Glayzer series is based on the sponge used in the Dignics series.
Spring Sponge X was developed to generate more power, increase response by 14%, and impact resilience enhanced by 3% compared to the original Spring Sponge.
Rubbers with harder sponges require faster swings that can bring out their speed and spin performance.
Rubbers with a softer sponge do not offer the same maximum speed and spin performance as a harder sponge, but it is easier for the rubber to hold the ball, making play more stable. It is easier to maximize potential.
- Hardness: 38 degrees
- Easier for rubber to hold onto the ball, making play more stable
- Does not require faster swings to maximize performance
- Uses a softer sponge than Dignics 05
- Suitable for a wide range of athletes and can greatly improve a players skills
