System 9 is proprietary software designed by Grafalloy's design engineers to calculate frequency, tip deflection, weight, balance point, swing weight, torque, EI and torque profiles based on flag design, materials, fiber angle and tooling. Each parameter change requires 100,000 new calculations to remodel the shaft's characteristics. System 9 ensures every Grafalloy shaft is designed with unparalleled material accuracy. Shafts can be System 9 designed to a player's specification and put into play on the PGA Tour in less than 48 hours.
