"THE NEXT GENERATION OF SPEEDER CONTINUES.Speeder NX Green accompanies the highly successful Speeder NX Blue, offering fitters an additional option to fine-tune player performance. Designed using our proprietary enso® motion caption software system, NX Green continues to utilize VTC (Variable Torque Core) Technology to refine twisting stiffness in specific sections of the shaft to promote excellent overall stability and specific ball flight characteristics.MID LAUNCH - LOW SPINA stiffened mid section further enhances overall stability and produces lower launch and spin compared to NX Blue.VARIABLE TORQUE COREA key technology featured in the Speeder NX line that leverages premium materials and advanced layup techniques to refine twisting in specific sections along the core of the shaft.ENSO®Fujikura’s proprietary motion capture system that enables us to efficiently analyze shaft designs and shaft performance data. enso® remains a core piece of our product development process.スペック"
