Equipment type: badminton racket. Equipment brand: Bonny. Equipment series: Uitra Deficit ZD series. Applicable scope: all. Price range: unknown yuan. Equipment description: Purple Flame Pro, Demon Slayer Pro. Bonny Purple Flame Pro. Release date: October 2024. Equipment introduction: Boron fiber middle tube, fish mouth front ferrule. Bonny 8888AX PRO in Uitra Deficit ZD series. 1. Low wind resistance small square head frame shape reduces air resistance during swinging and increases smashing speed. Increases sensitivity during swinging and sweet spot for hitting. 2. Boron fiber added to middle tube. High elasticity thin middle tube with a diameter of 6.8mm. Boron fiber has excellent impact resistance, high rigidity and excellent fatigue resistance to maintain weight and improve performance or reduce weight while maintaining performance. 3. Secondary molding. (1) Improves racket frame rigidity. A. Easily withstand high string tension. B. Effectively improves attack coefficient. C. Strengthens racket frame controllability with excellent ball control performance. (2) Effectively improves the torsional resistance coefficient of racket frame and middle tube. A. Strengthens ball control performance. B. Improves hitting feel. 4. Fish mouth front ferrule design. The middle pole is matched with power conversion. By limiting torsion, the structure of middle pole bending is enhanced, making it easier to transfer the power on the hand to the racket to help the stability and improve the flexibility of hitting. Racket frame material: high rigidity carbon fiber. Racket shaft material: high elasticity middle tube + boron fiber. Racket weight: 4U. Racket length: 675 ± 1mm. Grip thickness: G5. Middle tube toughness: moderate. String tension: ≤30LBS. Balance point: 300 ± 5mm.
