UHB SHAFT Extensive research and design has resulted in the UHB Shaft for improved badminton racket flex higher up on the shaft to provide extreme strength and control. The UHB shaft improves smash performance and is especially effective when hitting half smashes. STABILIZED TORSION ANGLE This feature implements a highly elastic design that is built into the badminton racket frame to reduce torsional forces caused by hitting outside of the sweet spot. The Stabilized Torsion Angle greatly improves accuracy and consistency with each and every swing.
