ZF sprockets are among the highest quality and most technically advanced sprockets in the world. The secret is based on the combination of the durability of steel and the lightness of duralumin. This aluminum alloy is characterized by enormous strength, durability and low weight. The tensile strength is approximately 11 times that of pure aluminum. With polymerization, duralumin reaches almost the strength of steel. As a result, lower weight and higher strength have been implemented. The milling in the base of the pinion tooth ensures optimal self-cleaning. These cuts ensure that dirt cannot get between the teeth and therefore the chain and sprocket do not spin as fast. The life of ZF-Dual sprockets is approximately three times longer than pure aluminum sprockets and 50% l.
