The 729 Battle series rubbers use the A-style hardness count. The higher the number, the harder it is. Its conversion to international standards is as follows.

37 = soft
38 = middle soft
39 = middle
40 = middle hard
41 = hard

What are the differences of rubbers of 729 Battle 2 Series?

The difference between the 729 Battle 2 series rubbers is the hardness and thickness of the sponge. Which is to meet the different preferences and habits of competitive players.

Recommendations for use

Battle 2 (regular): 38 and 39 are recommended for the backhand position for optimal performance;
Battle 2 (gold): Hard 2.15mm sponge, recommended for forehand position, can play the best performance;
Battle 2 (province): 38 recommended for backhand position, 39 or more recommended for forehand position, can play the best performance
Battle 2 (nation): 38 recommended for backhand position, 39 or more recommended for forehand position, can play the best performance

729 Battle 2 Rubber

Single adhesive covering technology;
Tacky surface;
Minor tower-shaped pimples;
Medium spaced particle structure.

Thickness: 2.1mm

Hardness: 38°(middle soft)/39°(middle)/40°(middle hard)

Speed: 12.5

Spin: 12

Control: 12

Forward: 13

Loop: 13

Sponge: Dense and high elastic internal energy preset sponge with orange color.

Performance:

"Control" to win

Anti oxidation adhesive surface and medium pimples spacing reduce the speed, increase the stability and rotation, and make the handling feel more soft.

The impact point of short court pushing and middle and back court looping is easy to control, which is suitable for loop driving with control.

729 Battle 2 Gold

Thickness: 2.15mm
Hardness: 40°(middle hard)
Speed: 13
Spin: 12
Control: 13
Forward: 13
Loop: 13
Rubber of Battle 2 gold are the same as Battle 2 regular. While the sponge is upgraded into Harder and Thicker, which is more suitable for the forehand.

Note:
The stiffening and thickening of the sponge requires minor adjustment of the matching and process, rather than simply thickening and hardening from a physical point of view.

729 Battle 2 Province

Thickness: 2.1mm
Hardness: 38°(middle soft)/39°(middle)/40°(middle hard)
Speed: 13
Spin: 12.5
Control: 13
Forward: 13.5
Loop: 13.5
Rubber: Same as Battle 2 regular
Sponge: Dense and high elastic internal energy preset sponge with blue and red color.
Performance:
"Spin" + "control" to win
729 Battle 2 Province added electronic temperature and pressure control to the sponge curing process, so that the sponge molding is closer to the optimal curing point. This makes the foam more uniform and has better elasticity. On the basis of no loss of control, the rotation and speed can be improved at the same time, which is suitable for loop driving with fast attack.

729 Battle 2 Nation

Thickness: 2.1mm
Hardness: 38°(middle soft)/39°(middle)/40°(middle hard)/41°(hard)
Speed: 13
Spin: 12.5
Control: 13
Forward: 13.5
Loop: 13.5
Rubber: the same as Battle 2 regular
Sponge: Dense and high elastic internal energy preset sponge with blue and red color.
Performance:
On the basis of Battle 2 Province, it meets the requirements of the national team and provincial team for equipment.
It has higher precision in thickness and hardness, smaller tolerance, and more stable performance, which is suitable for loop driving with fast attack.
