MonoGut ZX Pro 17G/1.22 String Black

Exceptional Dynamic Stiffness:
Dynamic stiffness provides playability similar to natural gut

Zero Polyester:
Absence of polyester increases elongation and decreases string bed stiffness

Dynamic Spin:
Optimum spin and resilience at all swing speeds

Minimal Tension Loss:
Zyex (polyketone) maintains tension better than polyester or nylon (polyamide) strings
