The Yonex Duora 77 badminton racquet is a solid all-rounder that gives users power and distance on both backhand and 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, and improved aerodynamics on the other side for faster racquet speeds and quicker returns. The balance is even and the frame length is extended by 10mm so leverage on all strokes is fractionally enhanced. The great strength and durability of the racquet comes from its graphite and nanometric construction which keeps it light, thin, stiff and strong.
