5U Weight — The Lightest Version of the Assassin
The BladeX Assassin is available in 4U and 5U configurations. The 5U sits between 75 and 79 grams — making it the lighter, faster option of the two. For players who prioritise speed of movement over raw power behind the shuttle, 5U is the clear choice.
At this weight, the racket swings with barely any resistance. In fast doubles rallies where the shuttle is travelling between players in under a second, that low swing weight translates directly into faster transitions — from defence to offence, backhand to forehand, net to mid-court. You’re not fighting inertia to get the racket into position. You’re just moving, and the racket moves with you.
The 5U is also the better choice for players who play long sessions or compete regularly. Less racket weight means less cumulative arm fatigue across a full match — which means your 21st point feels like your first.
SonicBoom Wind-Shedding Frame — Speed Through the Air
The frame of the BladeX Assassin uses Li-Ning’s SonicBoom technology — an aerodynamic frame profile specifically engineered to reduce air resistance as the racket head travels through the swing arc. When air drag is lower, the head accelerates more easily and reaches higher speed with the same physical effort from the player.
For defensive play and control shots, this matters because it allows you to generate enough pace on flat drives and net kills with a compact, controlled swing — no big backswing required. For quick exchanges at the net and fast repulsion play, it means your racket gets into position faster and comes back for the next shot sooner. The SonicBoom frame is the reason the Assassin feels effortless in rally situations where other rackets start to feel like hard work.
6.6mm MED High-Elastic Carbon Shaft — Responsive, Fast, Precise
The shaft of the BladeX Assassin is 6.6mm in diameter with a medium-elasticity carbon construction — and this combination is the heart of what makes this racket so well-suited to defensive and control play.
At 6.6mm, the shaft is ultra-slim — significantly narrower than the shafts on most badminton rackets, which typically sit between 6.8mm and 7.2mm. A slimmer shaft cuts through air with less resistance and returns to neutral position faster after each shot. That fast recovery is what makes the Assassin feel so sharp and responsive in quick exchanges. You hit one shot and the shaft is already ready for the next.
The medium elasticity is the key to the control character of this racket. A stiff shaft transfers power instantly but gives you very little feel for where the shuttle is going — errors happen faster and there’s less time to correct. A very flexible shaft gives lots of feel but delays the power transfer, which slows down your repulsion play. Medium elasticity sits between the two — enough flex to give you feel and dwell time on control shots, enough recovery to deliver clean, snappy repulsion on flat drives. It’s the shaft choice that suits a player who needs to do many different things well in the same rally.
Head-Light Balance — Maximum Manoeuvrability, Minimum Effort
The BladeX Assassin has a head-light balance with a 305mm balance point — mass sits towards the handle rather than in the head. For a defensive and control-focused player, this is the most important single characteristic of the racket.
A head-light balance makes the racket easier and faster to move. In defence, you’re often reacting to smashes coming at pace — the racket needs to get from one side of the body to the other in a fraction of a second. A head-heavy racket has too much inertia for that. The Assassin’s head-light setup means the racket is almost neutral in your hand — it goes where you direct it without any lag or resistance. For doubles players, net players, and defensive specialists, this is the balance that wins rallies.
Short Handle, Long Shaft Design — Power Without Force
The BladeX Assassin uses a short-handle, long-shaft construction — the handle is slightly shorter than a standard badminton grip, and that length is redirected into the shaft. For players who want to generate power without swinging aggressively, this design is genuinely useful. The longer shaft creates a longer lever arm between your hand and the shuttle at impact, which adds natural momentum to flat drives and clears without requiring extra physical effort from the player. Particularly beneficial on backhand drives where generating power efficiently is a known challenge.
Carbon Fibre Construction — Strong, Stiff, Stable
The frame of the BladeX Assassin is built from high-modulus carbon fibre — a material that gives the racket excellent torsional stability despite its ultra-light weight. When the shuttle strikes the frame during a net shot or a mishit, the carbon construction resists twisting and keeps the face square. This stability is what separates a carbon frame from cheaper alternatives — your off-centre shots are more consistent, and the racket holds its shape and feel through thousands of hours of play.
Two Colourways — Pearl White/Black and Green Bamboo/Black
The BladeX Assassin comes in two striking colour options. Pearl White/Black with pink accents is bold and clean. Green Bamboo/Black is distinctive and sharp. Both colourways carry the same technology and specification — the choice is yours.
