Focusopen NanoCarbon Pro 5U Competition Series Racket

The Focusopen NanoCarbon Pro 5U Competition Series Racket introduces Focusopen’s proprietary carbon nanotube reinforcement technology to the 5U weight category, delivering a frame that achieves competition-grade stiffness metrics at 15 percent lower density than conventionally processed carbon fiber, translating directly into superior player fatigue management over extended multi-match tournament formats. Carbon nanotube particle dispersion through the resin matrix at 0.5 percent by weight increases inter-laminar shear strength by 28 percent compared to unmodified carbon fiber composites, dramatically reducing the micro-delamination failure mode that causes hidden frame stiffness degradation in rackets subjected to high string tensions over tournament-season use cycles. Total unstrung weight of 77 grams in the 5U category with a slightly head-heavy balance at 298 millimeters suits attacking-oriented all-court play. The shaft diameter is 6.7 millimeters with a stiff flex rating of 76 kilogram-force for precise power transfer. Frame rated to string tensions of 32 pounds. Supplied unstrung with a premium padded individual racket bag and two replacement overgrip rolls. Focusopen applies a micro-textured anti-glare surface coating to all frame sections, reducing court-lighting reflection that can distract opponents during competitive service routines. The Focusopen logo and product designation are applied by sublimation printing directly into the resin surface layer, ensuring permanent graphic adhesion that does not peel or fade under regular playing and cleaning conditions.
