Then, attach the chainring securely to the crank with the 3 - bolt design. When riding, the narrow - wide tooth profile will keep the chain in place well, whether you have a Shimano or SRAM 11/12 - speed drivetrain. For maintenance, regularly clean the chainring with a mild bike cleaner and a soft brush. This will remove dirt and grime that can cause wear. Check the bolts periodically to ensure they are tight. If you notice any signs of excessive wear, like a lot of tooth damage, it might be time to replace the chainring. Also, avoid using harsh chemicals on the chainring as they can damage the aluminum finish.
