Using this SurRon Light Bee 58 Tooth Sprocket Chain Set is easy. First, make sure your bike is turned off and on a stable surface. Remove the old sprocket and chain carefully. Then, install the new 58 - tooth sprocket and the 420 - 112 Link O Ring Gold Chain that comes with the kit. When riding, keep in mind that the increased torque might change the way your bike accelerates. For maintenance, regularly clean the chain and sprocket to remove dirt and debris. Check the tightness of the chain often to ensure safe operation. If you notice any wear or damage, replace the parts promptly.
