Yonex | rexis speed – Yonex Rexis Speed | 1-30 White | OS

The YONEX Rexis is a polyester that’s been stretched under controlled temperature to deliver greater durability, reduced fatigue and consistent repulsion. The result is a control oriented string with more pop on every hit. The Rexis string provides improved power, repulsion and durability from the innovative FRF (Fusion of Resis Filament) production process. Upgraded at the molecular level for greater elasticity, the super-solid Rexis string structure is produced by filling the gaps of ordinary multifilament string with the new, more flexible material, FORTIMO, developed by Mitsui Chemicals, Inc. Resin is bonded to nylon filaments by plasma on a molecular level, improving repulsion and durability.
