Applicability: All
Price Range: Unknown yuan
Introduction Date: March 2023
Description: The Chengying Series, inspired by the tactical mecha ‘Chengying’ from the Chinese aerospace sci-fi IP ‘Nantianmen Project’ and ancient Chinese swords, symbolizes the inheritance of the speed of fighter jets and the sharpness of swords. The color scheme and paint finish of this series are different from the past, all采用ing a matte surface paint with unique colors. The different colored patterns intertwine around, making the racket’s appearance more sci-fi, harmonious, and dynamic without losing its stability, and possessing the temperament of a sword’s hidden light. The combination of various bright colors also symbolizes Bonny’s forty years of experience and growth into a professional sports equipment manufacturer focused on quality and innovation. Only by facing challenges can one see the rainbow, which is the philosophy Bonny wants to express through the ‘Chengying’ series. The three rackets in this series adopt different structures, covering most of the badminton playing styles of friends.
Parameter Introduction:
– Frame Type: Low air resistance frame, reducing air resistance during swing and increasing smash speed.
– Molding Method: The racket is made in three parts (head frame, carbon T-head, and shaft).
1. Racket polymer filling: Effectively increases the speed of power transmission in the racket. Polymer patent number: 20120225008.9
2. Carbon T-head: Carbon fiber T-head embedded at the three-way junction. Patent number: ZL200920306446.1
3. Shaft: Bonny’s patented conical shaft. Patent number: 201610342549.8
– The Bonny conical shaft moves the bending point up and down during the ball striking process, causing the frame to bend under force and transfer the force along with the gradual extension of the wall thickness, rebounding instantly and doubling the racket’s elasticity.
– The three main functions of the conical shaft (stronger elasticity, stiffer rigidity)
1. Ordinary shaft strength is generally 23-28kg, while the conical shaft’s strength can reach 33-38kg, making the conical shaft stronger and more durable.
2. Elasticity: The conical shaft returns to straight after bending in a shorter time, resulting in a greater smash force and a better non-vibrating hand feel.
3. Anti-twist force: The conical shaft’s 8kg anti-twist force is about 15-18 degrees, while the ordinary shaft is 22-25 degrees.
– Balance: The balance point is set at 0mm (unstrung) for a good hitting feel.
– Material Selection: 100% strict selection of frame material, high rigidity carbon fiber + carbon T-head + polymer filling.
– Shaft material: 46T + conical shaft + Wuque.
– Racket weight: 3U, 4U
– Racket length: 675±1mm
– Grip size: G5
– Shaft flexibility: Moderate
– String tension: ≤30LBS
– Balance point: 295±0mm
