What are Backside Table Tennis Rubbers?
Backside rubbers, also known as inverted or smooth rubbers, are one of the most popular types of rubbers used in table tennis. Unlike pimpled rubbers, backside rubbers have a smooth surface that allows for more contact with the ball, enhancing spin and control. These rubbers feature a sponge layer underneath the rubber sheet, which can vary in thickness and density, influencing the rubber's speed, spin, and control capabilities.
