About Specifications of Voltric Z Force II:
In India, Yonex Voltric Z Force is available in 4U weight option (it is around 83 gms). Racket frame is made of high modules graphite material while its frame is made of H.M. Graphite, EX-HMG, NANOMETRIC.
With 4U weight configurations, player can put string tension up to 30 lbs. for aggressive players, khelmart recommend the Yonex NBG 99 string.
Voltric Z Force II is revolutionary badminton racket from Yonex brand. It is a Voltric series badminton racket which provides incredible power to badminton players.
This Voltric series badminton racket is developed with ultra thin shaft which is extra stiff in nature. Due to extra stiff shaft and ultra dynamic head shape, player will get powerful smashes and easy 3rd line clear.
Yonex research shows that, Yonex VT Z Force II provide 6.2km/h more End shuttle speed as compare to tradition Z Force. With Z Force II, player will get 10 km/hr additional initial speed.
To improve the racket head speed and to improve the overall racket aerodynamics, Yonex used all new racket grommets design. With new design, now grommets are kept inside the frame which results into better racket aerodynamic and helps in extra racket head speed.
Voltric II Shaft use NANOMETRIC material which is technological advance and improved material having impact strength of 140 while stiffness is 98. Yonex Maximum Energy Transfer:
Yonex used ultra thin shaft in this racket which provide unique characteristics to z force 2. Additional to ultra thin shaft Yonex further improved the aero dynamic of racket by improve the aerodynamics of head. So the combination of ultra thin shaft and better aerodynamics of head provide increase in power and shuttle speed. Yonex Extra Slim Shaft:
By using extra slim shaft used improved the overall characteristics of racket. 8 % increase in bending strength, 40 % better impact strength. Yonex introduces the nanometric carbon technology in racket which improves the overall mechanical property of racket. Yonex Tri iBumper:
Shuttle contact to string bed is very important, Yonex clearly study the pattern of tradition Yonex racket shuttle contact and invented all new Tri ibumper technology. In this technology, tungsten infused grommets is used to maximum the shuttle contact with string bed. This improves the overall power of racket. Aerodynamic Frame:
In conventional racket, small part of grommets exposed to air due to traditional manufacturing technique. In order to reduce the air resistance, Yonex used infused grommets. Infused grommets are developed in such a way so that no part of grommets are expose to thus results into better aerodynamic of racket. Tri Voltage System Gives Powerful racket smashes:
Voltric series is head heavy series as per Yonex design. Head heavy series badminton rackets generate tremendous power on smashes as it leads to give more momentum. Further, to improve the head heavy racket characteristics, Yonex used stiff material at racket head which result into optimized shuttle hold time at string bed. By using stiff material at racket head, now player will get better power and control on shots. Yonex further improve the racket characteristics by making thin racket frame side. This improves the racket flex and help in transferring the more energy into shuttle. With more energy transfer, badminton player will get maximum power on shots.
Overall, the combination of head heavy, stiff racket head top and flexible side offer incredible power, speed and control to badminton players. Tri Voltage System Gives Speedy Racket handling:
In order to balance the head heavy effect of racket, Yonex first time used the very thin and aerodynamically shape side at frame head. This type of aerodynamically designed racket head side offers fast racket swing speed by which player gets quick racket response which helps in placing fast drive shots, quick corner smashes and quick response to opponent drives.
Overall, with the help of Tri Voltage System, Badminton player will get maximum power while player dont need to compromise on badminton racket speed. Sound Filter:
To improve the dull sound of shuttle hit, Yonex invented new technology known as sound filter. In this technology, new and innovative material is used at 10 o lock position. This reduces the unwanted and dull sound during shuttle hit and generates very clear and louder sound. Sound Filter also reduces uncomfortable sensation from the racquet by rapidly eliminating 31% of vibrations. Yonex Compact Frame:
To optimize its head heavy nature, Yonex used smaller size frame which results into better aerodynamic and provide better racket head speed. Smaller head size also reduces the drag forces and help in improving racket swing speed. Nanometric Shaft:
Yonex used Nanometric material in shaft which gives excellent shaft characteristics. It improves the bonding strength of carbon fiber and lesser carbon content in shaft helps in producing slim and thinner shaft. By testing Nanometric shaft on following results are observed:
1. Nenometric shaft gives 8% more Bending strength as compare to traditional graphite material.
2. 9 % better stiffness.
3. 16% better impact strength. Yonex Isometric:
Yonex isometric is a trademark technology for racket head frame shape. In isometric head shape, vertical string is kept as uniform length to produce extended sweet spot by horizontal strings. With enlarge and extended sweet spot, player will get better power on shots. Yonex New Grommets Patterns:
Yonex used innovative grommets patterns in this latest Yonex racket. It include single pass hole grommet which provide high performance string characteristics to better power and repulsion. Yonex Solid Feel core for better shock absorption, less noise and accurate shots:
Yonex first times used black micro core into upper part of badminton racket frame. Black micro core is dense material which serves as a damping device. This dense material is also stiff in nature which provides a vibration absorbing device. This device or material absorbs the unwanted vibration caused by shuttle impact and gives stable racket frame which helps in accurate shuttle placement. It is an innovative material technology which reduces the frame vibration up to a great extent. Yonex Unique Combination of Aero Box Type Frame:
Yonex Used combination of Aero and Box type frame for making the cross section of the frame. Box type frame construction gives better strength while aero type cross section offer better aerodynamics of racket frame. The combination of two certainly helps in improving the overall characteristic of the racket. Built in T Joint (More joint rigidity, better accuracy and control on shots):
Joint of any device is a weaker part and its affect the overall dynamic of the device. In Racket T joint is a weaker part and its affect the racket stability when shuttle hits the string bed. During shuttle impact on string bed, forces are transferred to T joint and if joint is weak in nature then it could cause direction instability of shuttle. Yonex identified this problem and developed built in T Joint. Yonex used Molded deep into the layers of graphite which gives joint free section and provide more rigid racket. Control Cap for Better Gripping and control on shots:
Control cap is a concept which is developed by Yonex to improve gripping of racket. Cap is a part which connect shaft with handle. Badminton player hold the racket from handle and finally grip its with Cap. Yonex used more flat surface on cap (88 PERCENT flat surface) which gives opportunity to grip more accurately.
