Equipment type: badminton racket. Equipment brand: Bonny. Equipment series: BONNY 1982 series. Applicable scope: all. Price range: unknown yuan. Equipment description: 1982B212, 1982B213. Listing date: unknown. Equipment introduction: B212 boron fiber midtube. Boron fiber has excellent impact resistance (result of high compressive strength), high rigidity, and excellent fatigue resistance. It can be developed in two directions: improving performance by maintaining weight or reducing weight while maintaining performance. Boron fiber has unique properties among existing reinforced fibers. In particular, its compressive strength is much higher than its tensile strength, which is not seen in other reinforced fibers. B213 four-axis midtube (stronger elasticity, stiffer rigidity). (1) Better strength and durability. (2) The midtube has a shorter time to straighten after bending, with greater smashing power and no vibration. (3) Better torsional resistance and smaller torsion angle. Parameter introduction: Frame type: Low wind resistance racket frame reduces air resistance during swings and increases smashing speed. Molding method: The racket is molded in three sections (head frame, T-joint, midtube). (1) Racket foaming process: Effectively increases the power transmission speed of the racket. (2) Carbon T-joint: Carbon fiber T-joint is implanted at the T-joint. (3) Midtube: Bonny’s patented four-axis midtube. B212 midtube is added with boron fiber. Three major functions of four-axis midtube (stronger elasticity, stiffer rigidity). (1) The strength of ordinary midtube is generally 23-28kg, while the strength of four-axis midtube can reach 33-38kg. Therefore, the four-axis midtube has better strength and durability. (2) Elasticity: The midtube has a shorter time to straighten after distortion, and the smashing power will be greater without vibration and with better feel. (3) Torsional resistance: The 8kg torsional resistance of the four-axis midtube is about 15-18 degrees, while that of ordinary midtube is 22-25 degrees. Balance: The balance point is set at ±0mm (unstrung), providing a good hitting feel. Uncut process: 100% strict screening of raw materials. Head frame design with nail arrangements at 2, 5, 7, and 10 o’clock. Racket frame material: High rigidity carbon fiber + carbon T-joint + polymer filling. Racket shaft material: B212 boron fiber + uncut for B212, four-axis midtube + uncut for B213. Racket weight: 3U, 4U. Racket length: 675±1mm. Grip thickness: G5. Midtube toughness: B212 (moderate), B213 (slightly hard). Stringing tension: ≤30LBS. Balance point: 295mm.
