The Yonex Duora 77 badminton racket is a solid all-rounder that gives users power & distance on both backhand & forehand play. This medium flex racquet has an Isometric head that works to increase the sweet spot size, & it has also been built using Yonex's Dual Optimum System which gives it a more box-like shape on one side for more powerful smashes & enhanced aerodynamics on the other side for faster racket speeds & quicker returns. This helps players dictate play on both forehand & backhand sides. The balance is even & the frame length is extended by 10mm so leverage on all strokes is fractionally enhanced. The great strength & durability of the racquet comes from its graphite & nanometric construction which keeps it light, thin, stiff & strong.
