Bumper from Pimplepark is a modern short pimples rubber designed for a variable offensive game near the table. Thanks to the grippy pips and the flexible, highly dynamic sponge, the rubber gives you properties similar to those of a regular backside rubber, without losing the benefits of being a short pimples rubber. Bumper gives you high control, medium bounce and a slightly disturbing effect. With thinner sponges, it is easy to play a passive blocking / counterattack game. With thicker sponges, the rubber gives you more speed and spin properties and then fits the more offensive player.
