Nippon NS PRO Zelos 7 The new Nippon Shaft N.S. PRO ZELOS 7 is a 74-gram steel shaft aimed at players who are seeking the stability and consistency of steel yet want the lightness and forgiveness of graphite. The stunning result is the N.S. PRO ZELOS 7, a new breed of shaft category that dispels the notion that “steel shafts lack shot distance in lieu of trajectory.” This extraordinary steel shaft combines world-leading light weight with sufficient flexibility and a low kick point that contributes to stable trajectory. Generating trajectory without power loss, its sweet spot keeps the launch at the right height for each club to ensure accuracy and stability.
