The Dunlop SX 300 tennis racket in another edition. This is a proposal for advanced players who are looking for a fast and precise racket.  The racket weighing 300 grams (unstrung) with a balance of 32 cm is a combination of maneuverability and dynamics. The head surface of 645 cm² increases the area of a clean hit - the so-called sweet spot - which improves the comfort of the game with off-center hits close to the frame. The open 16x19 stringing system increases the possibility of rotational play.In this edition, the SX collection uses Spin Boost + Grommets technology, i.e. shaped central grommets. Their task is to make it easier for the strings to hold and rotate the ball more tightly and to increase the range of rotation on a larger surface of the head. Sonic Core Technology with Infinergy, an exceptionally flexible material that provides a noticeable increase in vibration dampening. SPIN BOOST STRING TECH - reworked stringing system with larger spacing between the main strings (by 10%) and cross strings (by 11%). The result is greater movement of the strings, which allows for greater power and stronger generation of spin.SONIC CORE INFINERGY - located in two key areas of the racket, i.e. at 2 and 10 o'clock, dampening the shock of impact and reducing frame vibration by up to 37% better, which provides more comfortable strokes and reduces the risk of injury.V-ENERGY SHAFT II - Enjoy greater power and stability. Gain a more powerful stroke thanks to the optimized stiffness of the V-shaped cross-section.SPIN BOOST+ GROMMETS - directed grommets are now located on 12, instead of the previous version on 10 main strings at the top of the head. They allow greater movement of the strings in the direction of the arrows shown on the racket (forward and backward on some strings). Lateral (sideways) in one direction on other strings. This movement helps to bite the ball harder and generate high mechanical rotation - SPIN.
