Yonex ASTROX 77 Badminton Racquet (Shine Red) 4U, G5(UNSTRUNG)

The Yonex Astrox 77 badminton racquet turns head-heavy weight into usable attacking power, pairing a medium flex shaft with the Rotational Generator System so intermediate and advanced players can hit steeper smashes without fighting the frame. Finished in Shine Red and supplied unstrung in 4U with a G5 grip, it lets you dial in your own string and tension before your first match.

Attacking Power from the Rotational Generator System

Yonex distributes weight across the grip end, frame top and T-joint so the head loads momentum through the swing and settles quickly afterwards. The result is a racquet that pushes clears deep and drives smashes down at a sharper angle. Yonex swing-robot testing rates the Astrox 77 at 7.1 percent higher smash power and a smash angle 2.3 degrees steeper than its predecessor.

Frame and Shaft Built for Repulsion

The frame combines HM Graphite, NANOMETRIC and Tungsten, while the shaft pairs HM Graphite with Namd graphite for faster snapback on impact. A built-in T-joint and 10 mm of extra length add stability and reach, and the medium flex rating keeps the racquet friendly rather than punishing.

Forgiveness Where It Matters

The Isometric head squares off the top of the frame to enlarge the sweet spot. Players moving up from an entry-level racquet consistently report fewer frame hits and cleaner contact on off-centre shots, which is exactly what a head-heavy badminton racket needs if it is going to stay usable in long doubles rallies.

Unstrung, So You Set the Feel

This is the unstrung 4U G5 model. Yonex advises a string tension of 20 to 28 lbs for the 4U frame: lower tensions add repulsion and comfort, higher tensions sharpen control. Choosing your own string means the racquet matches your technique rather than a factory default.

A Yonex Racquet for UAE Courts

Indoor club badminton in Dubai, Sharjah and Abu Dhabi runs year round in air-conditioned halls where fast, attacking play dominates. The Astrox 77 suits players who want to finish rallies from the rear court rather than grind them out. Sea Wonders stocks it in the Shine Red colourway with delivery across the UAE.
