Riblets are a type of surface geometry that cause a reduction of frictional resistance on surfaces with friction.
The surface geometry of riblets for example can be found on the scales of sharks. 
We have been inspired by this phenomenon and have incorporated it in our new antispin rubber B.A.D Best Anti Defence in a globally unique manufacturing process. The result is unique and amazing:
In the ralley, the incoming rotation is preserved, but the dreaded angle dependency with balls with little rotation is nearly eradicated entirely. This results in virtually perfect control. This unique anti-spin rubber also enables relentless attacks on all types of spin and no-spin balls.
B.A.D. Best Anti Defence is available in red and black with 0.7mm, 1.1mm or 1.5mm absorption sponge.
The 1.5mm version is the slowest.
Glue this rubber only with the MSP-DK4 adhesive foil as described in the attached mounting instruction. 
Note on the use of plastic and ABS balls:
In addition to the perfect use with celluloid balls, all of our smooth ANTI TOP rubbers also produce maximum spin reversal and a very high disruptive effect with the new plastic and ABS balls.
