This is a black version of the 2021 release Head Graphene 360+ Speed MP Djokovic Limited Edition. It's a set of 3 G2 rackets with adjusted specifications. The head size is 100 sq. inches with a 16x19 string pattern. Purchases from different accounts will be declined to prevent any issues. Specs A and B, including overgrip and string weight, are 333g, 319mm balance, and SW 332.5 (original specs before stringing: A was 298g, 320mm balance, SW 295; B was 299g, 322mm balance, SW 298). Spec C, including overgrip and string weight, is 333g, 320mm balance, and SW 333.5 (original specs before stringing: 297g, 318mm balance, SW 286). The original grips on all 3 rackets have been replaced with new Head HydroSorb grips one week ago. The seller has repeatedly requested modifications from Mr. Murai, a famous racket master in Chiba, and has mastered the theory and techniques of specification adjustments. The seller now adjusts commercially available rackets and uses them. The reason for adding lead tape is to play competitively, allowing for easier ball flight and more powerful shots. Players at the intermediate to advanced level and above should be able to experience shots similar to those of professionals. The specifications and balance have been calculated and adjusted, making these rackets similar to those with Tennis Topia specs. You will find that these rackets are easier to hit with than commercially available ones, allowing for easier adjustment of ball flight without unnecessary force. The lead tape is primarily applied at the 11 and 1 o'clock positions on the head and at the bottom of the handle after removing the original grip. If you wish to remove the lead tape, please do so after purchase. The specs will change, but the racket will return to its original commercial specifications. The strings for A and B are strung with Babolat VS Touch 130 at 52 lbs (mains) and Babolat Blast 125 at 49 lbs (crosses) by Windsor. C is strung with Babolat VS Touch 130 at 52 lbs (mains) and Luxilon Alu Power Rough at 49 lbs (crosses) by Tennis Way. The strings were used last week, so they should still be usable. Rackets A and B have been used 5 times since purchase. Racket C has been used 2 times since purchase. All 3 rackets are considered to be in excellent condition. Finally, please understand that these are used items, and purchase accordingly. No returns or exchanges are accepted. The rackets will be shipped together in a single racket box. A grommet set is available in stock and will be included as a service. Thank you for your interest.
