The R53 is the first rubber with the newly developed andro ENERGY CELL sponge that charges every topspin with outstanding dynamics.
R53 break with conventions, use the strengths of the andro ENERGY CELL technology: more power with hard topspins and game openings on backspin, high dynamics and longer ball contact time to be felt.
The andro ENERGY CELL sponge is designed with highly elastic cell structure ensures an extremely dynamic energy transfer, especially for fast and hard topspins.
The 53° sponge provides immediate feedback on ideal ball contact.
The R rubber surface gives maximum rotation gains additively more impact through the ENERGY CELL sponge.
