The Voltric i-Force badminton racket is designed based on Yonex most popular and best-seller racket, the Voltric Z-Force. The racket does not have stiff shaft and the advanced material such as NanopremeTM, but it does the Z aerodynamic head shape and have pretty good swing feel similar to the Z-Force. The i-Force overall weight is much lighter at 5U ( average weight of 78 grams ) compared to the Z-Force at 4U ( average weight of 83 grams ) and, yet, offer a head heavy swing weight close to the Voltric 70 & 80. These combine specifications make the Voltric i-Force much easier racket to play while offering pretty good power close to the popular Z-Force.
Traditionally, extra weight at the top of the racket frame has increased power while reducing maneuverability or control from the player. In contrast, less weight on the top of the racket frame increases speed but reduce power. Yonex solves this problem by using the new TRI-VOLTAGE SYSTEM to successfully combines the contrasting characteristics of exceptional power and control.
Within the TRI-VOLTAGE SYSTEM, Tungsten inserts are positioned at the 2 and 10 o'clock positions of the frame, and at the T-Joint area. Tungsten provides more than 10 times the relative density of graphite, allowing the sides of the frame to be thinner and more aerodynamic and therefore achieving the combination of heavy smashes and swing speed or fast racket handling.
