YAMAHA ヤマハ 2025 RMX DD Driver Compatible Sleeve with Mitsubishi Chemical Diamana Stinger Mid-Kick Reissue Model Golf Shaft

The Mitsubishi Chemical Diamana Stinger is a driver shaft that revives the legendary prototype from the first Diamana series developed in 2004, incorporating the latest modern materials and design technology. Based on the popular mid-kick point design of the Diamana series, it is a culmination of years of research and evolution.

Its most prominent feature is the luxurious use of boron, a high-strength material also used in aircraft, and DIALEAD, a high-modulus pitch-based carbon fiber, throughout the entire 46-inch length of the shaft. This results in incredibly smooth and consistent shaft behavior during the swing, allowing anyone to achieve a stable swing-through with minimalクセ (unpredictable movement).

At impact, the flexible behavior generates a firm feel and powerful repulsion, increasing ball speed and creating a strong, penetrating trajectory. The excellent balance characteristic of a mid-kick point makes timing easy, suiting a wide range of swing types.

The lineup includes three weight categories: 53, 63, and 73. The 50g range offers excellent swing-through and speed performance, the 60g range is a balanced and standard specification, and the 70g range is a model focused on powerful trajectories and stability.

Inheriting the feel of a classic shaft cherished by golfers for many years, this new generation Diamana achieves further performance improvements with modern technology. It is a high-performance shaft recommended for golfers seeking both distance and control.
