The Dunlop Tennis Biomimetic 500 Tennis Racquet is a new addition to the Biomimetic range with a 100 square inch head for power and control. The 500 model has been a very popular introduction to the range with the 10.29 ounce weight, making it extremely agile around the net for perfect volleys while the tapered beam and open 16 x 18 string pattern give access to plenty of power and spin.
