Loki Rxton 7 Zhao Zihao (National Pro Special Version)

Kunlun Sponge II sticky rubber, upgraded with 20% higher energy efficiency, complex arc.

This rubber comes from the Loki Rxton range, A40 sponge hardness, available in 2.1mm sponge thickness.

Tacky rubbers grip the ball directly off the sponge, which favours spin generation and close-to-the-table play, typically with a shorter, more controllable throw angle.

Best suited to competitive players with fast, well-timed strokes who can control the extra speed and spin on offer.

As a guideline, match sponge hardness to your own contact power: harder sponges reward players who can generate their own speed, while softer sponges are easier to control and better suited to a slower, more compact stroke.
