ONOFF AKA KURO Driver Compatible with TENSEI Pro Black 1K Core Series

¥33,000 Save ¥-33,000

Introducing the TENSEI Pro Black 1K Core Series, a high-performance carbon shaft for drivers developed for professional athletes. Its main feature is a structure that places a highly drapable 1K cloth in the inner layer (core), providing the shaft with extremely high dimensional stability and reinforcement.

The overall shaft design allows the softness in the butt section to create a natural "lag" during the swing transition, efficiently accelerating energy towards impact. The mid-to-tip section features a high-rigidity design, minimizing face deflection and enabling a solid, powerful impact. This achieves both a highly reproducible swing and excellent distance performance.

In addition to the all-black shaft design, the jet-black band creates a beautiful finish that appeals to advanced players. This shaft is ideal for competitive golfers and single-handicappers who seek a stable feel and direction. Experience the reliability of Made in Japan, utilizing the latest material technology.
