An unplayed Yonex Duora 10 4UG5 badminton racket, famously used by former world number one Lee Chong Wei, has been listed for sale on Marktplaats after being forgotten in a residential attic.
Unused Badminton Racket Features Dual Optimum System
The Yonex Duora 10 gained international recognition as the weapon of choice for Malaysian legend Lee Chong Wei during his professional career. According to Marktplaats listings, the specific item currently offered features a 4UG5 grip size and remains in unplayed condition. The seller reports discovering the equipment tucked away in an attic storage space.
Market availability for the Duora series changed significantly after Yonex officially discontinued production of the model. Because the frame is no longer manufactured by the company, finding an unused specimen on secondhand platforms has become rare. The sale includes the original racket cover, though the seller notes minor damage on the casing visible in the final photograph of the listing.
Asymmetrical Frame Combines Box and Aero Shapes
The defining technical characteristic of the Duora 10 is its proprietary Dual Optimum System, which utilizes an asymmetrical frame geometry designed to support contrasting stroke techniques. Marktplaats details note that the two sides of the frame feature distinct visual color codes—such as orange and green or blue and pink—allowing players to identify the orientation during fast-paced rallies.
The forehand side employs a traditional square box frame. This construction supplies structural stability and maximizes power transfer during high-velocity shots like smashes. Conversely, the backhand side utilizes an aerodynamic aero frame profile. This sharper, tapered edge reduces air resistance to deliver faster racket head speed and increased repulsion during rapid drives and defensive returns.
Stiff Flex and Even Balance Define Specifications
Technical specifications for the 4UG5 model place the frame flexibility firmly in the stiff category. Marktplaats data indicates the balance point is even, though certain players experience the weight distribution as slightly head-heavy depending on string tension and grip modifications.
