The Yonex Nanogy 98 (NBG-98) has a sharp feeling with 0.66mm gauge. The Yonex Nanogy 98 (NBG-98) string has excellent repulsion for high clear and defensive shots. The NBG-98 uses an original Carbon nano Fiber that gives powerful repulsion combined with high durability. The Nanogy 98 (NBG-98) is suited for players who look for resilience to increase speed and durability for longer lasting string.

The YONEX Carbon Nano Fiber construction which has four times more elasticity than a carbon nanotube combined with a high-strength nanofiber coating, minimizes notching of the string at intersecting points. This construction achieves increased durability and high repulsion power.
