This series of shafts feature two key technologies: Low Resin Content (L.R.C.) Prepreg and Titanium Nickel (TiNi) Wire. After first using TiNi Wire in our ultra-light products, we wanted to see how it would perform in heavier, tour-weighted shafts. KURO KAGE™ - fiber plus wire equals power.
The shaft that started it all. Diamana™ continues to be a proven performer trusted by many pros because of its consistency and ability to deliver under pressure. And, most importantly, because we never stop improving it as we develop new, advanced materials.

These shafts are not just re-engineered, lightweight versions of our heavyweight models. They’re specifically designed to use our most innovative materials in new ways, providing great stability while shaving off precious grams.
The OT™ Iron shafts originated in Japan in our "idea lab" called FRANKI™ named for the Japanese word for incubator - "Fooranki". This group of designers, engineers, tour reps and other specialists spend their time and energy creating new ways of doing things. No matter how crazy they seem.
