N.S.PRO Zelos7 Iron.355 Taper, R-Flex, for #6 (37.0"), Single Shaft

The Nippon Zelos 7 Steel Shaft's 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, however, we committed ourselves to solving this dilemma by developing a new type of steel. Even though stronger steel commonly decreases flexibility, and greater flexibility commonly decreases strength, we set our minds on developing a steel material that would deliver both greater strength and greater flexibility. After a long, arduous struggle of trial and error, we finally developed a new material that offers impressive light weight, strength and tenacity. We then concentrated our efforts on maximizing the new material’s potential and invested our technological expertise, gained through extensive experience, to develop a ‘light and pliable steel shaft’. After two years of continuous development effort, we proudly introduce a new Nippon Shaft ultra-lightweight steel shaft category
