Rare Tennis Topia SPEC 3. The current specs, including the strings, are 355g, 315mm balance, and SW336. The report for this product was not included when I previously purchased it on Mercari. This is a Pro Staff RF model tennis racket in black, offering high performance. It's the model used by Federer when he won the 2017 US Open. It has a custom tune from Tennis Topia, resulting in a different balance than the standard model. You can achieve effortless swings and hit balls with overwhelming power. The feel of the ball strike is also different from the standard model, feeling softer. Also, the ball seems to lift more than with the standard model. - Model Name: PRO STAFF RF97v11 - Brand: Wilson - Color: Black - Grip Size: 3 - Weight: 336g spec3 I think it's in relatively good condition, but please check the photos before making your purchase. I've only used it 2-3 times. The strings are: Vertical - Yonex Poly Tour Strike 130 at 55p, Horizontal - Luxilon Alu Power Rough 125 at 52p, strung on November 15th. It has three leather patches and ten elastocross strips applied in the same positions as Federer's racket. Although it is in good condition, please understand that it is a used item before purchasing. I will ship it in a racket-specific cardboard box. No returns or exchanges. Thank you very much. Thank you for viewing.
