Focusopen PowerSmash 4U Heavy Hitter Racket

The Focusopen PowerSmash 4U Heavy Hitter Racket is developed for singles players with physically powerful swing mechanics who want to translate their natural athletic strength directly into maximum shuttle velocity during rear-court attacking play. The 4U weight class at 86 grams unstrung combined with an extreme head-heavy balance at 320 millimeters creates a swing-weight characteristic that generates exceptional shuttle exit velocity from jump smash positions at the cost of reduced maneuverability, making the PowerSmash 4U the specialist choice for players who win points predominantly through power dominance. The frame is manufactured from 42-ton high modulus carbon fiber with an asymmetric cross-section in the upper quadrant that increases vertical bending stiffness while allowing controlled lateral torsion for serve spin and cross-court angle generation. The reinforced throat piece uses a dual-layer carbon overlay bonding technique that eliminates the flex characteristic common in longer-shaft geometries. The extra-stiff shaft at 7.0 millimeters diameter with a 90 kilogram-force stiffness rating ensures that no energy is absorbed during the power-application phase. Strung at 28 pounds with Focusopen PowerLine 0.68mm string. Full-cover bag included. The Focusopen quality assurance process subjects every unit to a 12-point inspection covering frame symmetry, string plane flatness, grip wrap adhesion, and label registration before packaging.
