TIBHAR Grass D.Tecs GS rubber with the built-in D.TecS effect in our classic grass long pimples, you will encounter new variations of the undercut and cut alternating repellent. Thanks to the built-in tension in both the nub rubber and the sponge, the nubs become more elastic, which creates an incredible undercut. On the other hand, due to the softness of the surface, the D.Tecs effect ensures that you have excellent control in the defence and have enough speed in disturbing attacks at the table to bring the opponent out of the rhythm with restless attack balls.
