NANORAY Z-SPEED racket with high-speed performance. - Model Name: NANORAY Z-SPEED - Weight: 3U/20-27 lbs - Grip Size: G5.9-12.0kg Thank you for viewing. Please check the photos for scratches. There is a deep scratch in the 13th photo, so I'm offering it at a low price. This is a top-of-the-line model in the NANORAY series that enables overwhelming speed smashes. It is also known as the racket that set the world record for smash initial speed (493km/h at the time). Technologies such as "Horizontal-A Concept" and "SBZ (Snap Back Zone)" expand the sweet area and achieve explosive acceleration. The compact frame design allows for easy swinging and has the performance to handle high-speed rallies. The shaft is stiff, and it is considered a model for intermediate to advanced players with a certain amount of power. NANORAY Z-SPEED
