Selling 3 months old Wilson N90, Strung with yonex BG-68Ti @ 22lbs. Grip had never been use as i used an overgrip. This racket was very rarely used as i bought it as a back up racket. Other than the two little paint chip, the condition is perfect. The racket bag that came with the racket had never been use, the bag have a integrated shoebag built into it. Racket alone:S$70 Racket + Bag: S$80
I don't think so. As muscle power is developed by yonex, I don't think wilson is entitled for the technology.
