Light weight and strength have been mutually exclusive. Reducing the weight of steel has lowered its strength, increased the likelihood of breakage and reduced the pliability required to make dynamic shots. Two years ago, Nippon Shaft committed to solving this dilemma by developing a new type of shaft. Even though stronger steel commonly decreases flexibility, and greater flexibility commonly decreases strength, the aim was to develop a steel material that would deliver both greater strength and greater flexibility. After a long, arduous struggle of trial and error, Nippon finally developed a new material that offers impressive light weight, strength and tenacity: NSNS60.
The result of maximising this new material’s potential for an ultra-lightweight steel shaft category resulted in the N.S. PRO Zelos 7, an easy to handle shaft with an extremely smooth swing and gentle touch, combined with the exact swing characteristics of a graphite iron shaft.
Inspired by Zelos, the Greek god of rivalry, the name Zelos was chosen to to encourage competitiveness among steel-shaft users who relentlessly seek progress. Designed with a low kick point and evenly distributed rigidity, more than ample flexibility is delivered from tip to butt. As the world’s lightest steel shaft, Zelos employs newly-developed, cutting-edge, high intensity NSNS60 material that delivers the smooth control and performance of high-carbon material.
