The Supersprox Stealth sprockets are the highest quality and most technologically advanced sprockets in the world. The secret is based on the connection of the resistance of steel and the lightness of duralumin. Duralumin is mainly used in aviation and has compared with pure aluminum has a slightly larger density. The tensile strength is about 11 times of pure aluminum. The hardening of duralumin almost reached the strength of steel. been implemented is therefore a lower weight and higher durability.The center parts are manufactured with high precision on CNC milling and coated with a thick Eloxalfilm, prevents oxidation. Anodizing is (electrolytic oxidation of aluminum). It is converted into an oxide layer in an electrochemical process, the surface of the aluminum workpiece. This layer is defined in its thickness and makes the products thus treated wear-resistant and corrosion-resistant. After experiences keep the Stealth Sprockets about three times longer than pure aluminum sprockets and are 50% lighter than steel sprockets.
