Prince Phoenix Y 1200 Team Badminton Racket 82g (4U) Triple Threat - Triple Threat system perfectly matching Y-Frame geometry to produce great balance and stability by placing a combination of weighted materials in 3 critical racquets location: at the 10 o'clock, 2 o'clock and in the handle. The end result: Expanded sweet spot with less shock to the arm and better off center hitting. Perfect balance and stability in a racquet that will improve your game. Y Joint - The Phoenix frames have a short shaft due to the 'Y' construction and combined with its narrow tapered shaft produce a frame with exceptional speed and dynamic response. The patented 'Y' Joint design provides superior torsional stability, because the head portion connects to the shaft at an angle, allowing bending and torsional stresses to be balanced. In additional the 'Y' design provides longer strings resulting in an expanded power zone. ESP - Extreme String Pattern (ESP) is a unique string pattern to Phoenix badminton frames, with the more open pattern providing more string bed deformation and repulsion for more powerful shots with great striking feeling. Top Aero + Bottom Box Frame - Box shape 'Y-limbs' increase the torsional rigidity of the frame, provide superior lower hoop stiffness and strength to support high tension stringing. Aero shape in the tip of the hoop allows greater maneuverability and greater racquet head speed generation. Isomectric head frame - Equalizes the length of main and cross strings in the stringbed, enlarging the sweet-spot for more consistent accuracy even on off-center hits.
