Equipment type: badminton racket. Equipment brand: Bonny. Equipment series: Chengying series. Applicable scope: all. Price range: unknown yuan. Equipment description: Chengying Gold. Listing date: March 2023. Equipment introduction: The sharp blade emerges with a glint. The jade dragon is sharpened and the sword is Chengying. The ‘Chengying’ series is a new series created by Bonny after more than forty years of honing. Currently, there are three rackets in this series. The inspiration comes from the ‘Chengying’ tactical mecha in China’s aerospace science fiction IP ‘Nantianmen Project’ and ancient famous swords in China. It implies inheriting the speed of fighter jets and the sharpness of swords. The color schemes and paint finishes of this series of rackets are also different from before. They all use matte paint on the surface. The colors are unique and break the previous racket style of Bonny. Different colored patterns are intertwined, making the appearance of the racket more sci-fi, harmonious, dynamic yet stable, and with the temperament of a sword’s light not yet unleashed. At the same time, the combination of various beautiful colors also symbolizes that after countless hardships over forty years, Bonny has grown into a professional sports equipment manufacturer that focuses on quality and insists on innovation. Only by not fearing wind and rain can one see the rainbow. This is also the concept that Bonny wants to express through the ‘Chengying’ series. This time, all three rackets adopt different structures, covering most of the playing styles of badminton players. Parameter introduction: Frame type: Low wind resistance frame reduces air resistance during swings and increases smash speed. Molding method: The racket is molded in three sections (head frame, carbon T-joint, middle tube). (1) High molecular filling of racket: Effectively increases the power transmission speed of the racket. High molecular patent number: 20120225008.9. (2) Carbon T-joint: Carbon fiber T-joint is implanted at the three-way joint. Patent number: ZL200920306446.1. (3) Middle tube: Bonny’s patented tapered middle tube. Patent number: 201610342549.8. During the hitting process of Bonny’s tapered middle tube, the bending point of the racket will move up and down, so that when the frame is bent under force, the force is transferred along with the gradual extension of the wall thickness, instantly borrowing force to rebound and doubling the racket’s elasticity. Three major functions of tapered middle tube (stronger elasticity, stiffer rigidity). (1) The strength of ordinary middle tube is generally 23-28kg, while the strength of tapered middle tube can reach 33-38kg. Therefore, the tapered middle tube has better strength and durability. (2) Elasticity: The time for the middle tube to straighten back after being distorted is short, and the smashing force will be greater and the feel is better without vibration. (3) Torsional resistance: The 8kg torsional resistance of tapered middle tube is about 15-18 degrees, while that of ordinary middle tube is 22-25 degrees. Balance: The balance point is set at ±0mm (unstrung), providing a good hitting feel. Unique technology: 100% strict screening of raw materials. Frame material: High rigidity carbon fiber + carbon T-joint + high molecular filling. Shaft material: 46T + tapered middle tube + unique. Racket weight: 3U, 4U. Racket length: 675±1mm. Grip thickness: G5. Middle tube toughness: Moderately hard. Stringing tension: ≤30LBS. Balance point: 305±0mm.
