Yonex Voltric 1 LCW VT1LCW 4UG5 Badminton Racket (4U) 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. Tri-Voltage System - The stiff racquet structure at the top of the frame allows the head to bend in a very controlled way and hold shuttles on the string bed for longer. The thin frame sides then allow the frame to flex more and transfer more energy to the shuttle. This combination allows you to smash with instant power. In VOLTRIC, the weight is balanced on the top of the frame and at the joint area which allows good handling while also maintaining power. The thin sides of the frame and at the top of the head reduce air resistance and improve the handling even further. Players can now make a full swing even during short range rallies as VOLTRIC responds instantly to even subtle movements. Built-in T-Joint -	Moulded deep into the layers of graphite where the frame connects with the shaft, the YONEX Built-in T-Joint creates a durable and high-strength one-piece frame that is torque-free. Control Support Cap -	The control support cap provides an 88% wider flat surface compared with an ordinary racquet for easier gripping, fast follow-through and the sharpest maneuverability.
