Diabolic is an antispin rubber that seeks to emulate the properties of a long pip rubber. Namely the low and disruptive trajectory long pips are known for on blocks. The dampening sponge reduces speed and allows for high control. IMPORTANT- Glue all Der Materialspezialist antispin rubbers with the glue sheet (should be ordered separately) using the instructions provided. If instructions are not followed, refund claims for damaged antispin rubbers will not be honored.
