Hey bike repair folks, this little 13-tooth chain sprocket is one of those basic parts that's good to have around. Made from solid carbon steel, it's built to handle regular use without wearing out too quickly. The teeth are spaced at 12.7mm with a 3mm thickness, which is pretty standard for most ordinary bicycles. The inner diameter is 11mm and it fits chains that are 1/2x1/8 model type. It's specifically designed to work with 1016Z2 and 1016Z3 reducer motors if you're doing motorized bike projects. The whole thing measures about 58mm in outer diameter and 9mm thick, so it's compact and lightweight. Installation is straightforward - just swap out your old worn sprocket and you're back in business. The teeth are cut cleanly and the finish is smooth, which helps with consistent performance and reduces chain wear over time. Whether you're maintaining your daily rider or working on a project bike, having a reliable replacement sprocket like this can save you from being stranded with a skipping chain. It's one of those simple components that just works without any fuss.
