Finding the flexibility and bounce of the ball.

Following a nine-year research project, the Spring Sponge X was developed to create a more powerful shot.
Sponge springs have a 14% increase in response with a 3% increase in elasticity compared to current sponge springs.
The result is a noticeable difference in strength gains.
Spring sponge X is the key to bringing high performance to DIGNICS tires.

Why it’s important to use both resilience and rebound

– High compression resilience of the sponge is required. to create a high degree of rotation combined with stability In addition, the sponge must be flexible in order to create a powerful hit.

– Soft sponge features that can be easily responsive. But the energy impulse generated was very small. On the other hand, a harder sponge can increase its elasticity. But it’s hard to suck the ball on the tire. due to less flexibility

– Spring sponge, introduced in 2008 and applied to the TENERGY series, is revolutionary in terms of achieving a combination of agility and high flexibility.

– The spring sponge X has been optimized for both high agility and resilience. which is the key to bringing the highest level of performance to DIGNICS tires.

Compression reaction and elasticity of each type of sponge

Using a sponge of 40 hardness to create more power.

The result of the pursuit of more strength and power. The hardness level of the sponge used is hardness level 40.
Compared to the TENERGY family of sponges, it has 4 levels of increased hardness.
However, with the development of the level of mobility that gives a soft feel even though the rubber has a hardness of 40
In general, the stiffer the sponge, the heavier the weight of the rubber.
But Spring Sponge X is the same weight as Spring Sponge used with TENERGY, even though it is 4 levels harder.
But when attaching DIGNICS rubber to the wood, the wood will not be too heavy.
Although attached to the wood on both sides. It can be easily used by less powerful shooters. without problems
