Matrix Radix S 5 Series Graphite Wood Shafts
RADIX is Latin for "base" or "root". The base for RADIX is The HD design, giving RADIX the most advanced internal structure in its class. Along with the internal structure, an experimental variable tip-to-butt ratio design is introduced with RADIX. The ratio specs change by flex - ball flight lowers as flex stiffens, adjusting for the progressive needs of progressively harder swingers.
