This piton features a lightweight and compact design. By using ultra-super duralumin for the material, high strength and weight reduction are achieved. The specific gravity is only 2.8g/cm3, less than half that of stainless steel at 7.93g/cm3, making it lightweight. Furthermore, the tensile strength is approximately 570N/mm2 for ultra-super duralumin, compared to approximately 520N/mm2 for stainless steel, boasting high strength. Produced with high-precision CNC machining, there are no welds, reducing the risk of breakage. Shaft Length: 30cm (16mm diameter) Material: Ultra-super duralumin (bolts and nuts are titanium) Weight: 341g (including shaft)
