The use of narrower pimples in a dense arrangement on the top rubber was the key to the successful design of the Tenergy 19. The result is a surface that is on the one hand tight enough to prevent the rubber from slipping at high impact, but on the other hand gives a unique feeling of "holding on" at ball contact. The Tenergy 19's rotational ability and precision have been further improved compared to the Tenergy 05, giving the rubber excellent playability in both active and passive play.
