Der Materialspezialist DIABOLIC EXTRA SLOW is one of the slowest and most disruptive frictionless anti-spin rubbers developed for maximum spin reversal and extreme speed absorption.
Its ultra-slow high-tech sponge technology absorbs incoming speed exceptionally well and produces a very dangerous low and wobbling ball trajectory. The ball sinks heavily after blocking, making the opponent’s next attack extremely difficult.
DIABOLIC EXTRA SLOW is highly insensitive to incoming spin and provides outstanding control in blocking, short play and defensive situations. The slightly harder sponge additionally improves the spin reversal effect and creates a more direct playing feeling.
An excellent choice for anti-spin players seeking maximum disruption, ultra-low speed and elite control
