The Supersprox-racing steel sprocket will run 20,000 miles on the street, with the right chain combination. Remember that a worn alloy sprocket WILL prematurely destroy your chain life! What tech about this sprocket Start with the steel. We are using high carbon steel with a core strength of 400MPa, meaning the sprocket teeth will not bend or deform, even on the most powerful bikes. Every part of the sprocket has been machined to ensure perfect flatness and roundness. To make your sprocket, we will use the following. Laser cutter, CNC lathe, CNC mill, 19 flattening rolls, a surface grinder, a tooth cutter and another laser to write on the surface. The black surface finish is not just for looks. It is a super technical process that prevents corrosion on the teeth by forming a zinc carbonate barrier. After this first process, the sprocket is silver. Our competitors usually add paint to make their parts black, but that rubs off after a few miles and looks terrible. We make it black, by adding another technical layer called Trivalent Chromium and this micro thin layer bonds to the zinc base, giving more corrosion protection and looks much more technical than plain old paint. – You are really getting more for your money! Want STRONGER teeth Supersprox have developed several unique products over the past 45 years. We have also pioneered the way forward in technical design. Back in 2004, we introduced a special tooth design that increases chain contact and significantly extends the sprocket life. – Its an exclusive feature!

About the black plating: Hot-dip galvanizing is a form of galvanization. It is the process of coating iron, steel, or aluminum with a thin zinc layer, by passing the metal through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a "spangle").
