Promax presents this amazing 4 - Bolt Chainring in sleek black. Crafted from high - end 6061 - T6 series aluminum, it's built to endure the torque and stress of modern BMX racing. Plus, it works great in other single - speed applications. It's CNC machined, offering high strength while saving weight. This chainring is designed to fit most cranksets and spiders that use a 4 - bolt 104 BCD chainring. Technical specs include a black color, single ring position, 42 teeth, round shape, single - speed 3/32' drivetrain, 104 BCD, and an aluminum material.
Using this chainring is easy. First, make sure your crankset or spider is compatible with a 4 - bolt 104 BCD chainring. Then, simply attach the chainring securely to it. When using, be aware that this is a single - speed chainring, so it's designed for specific types of bikes and riding styles. For maintenance, regularly clean the chainring with a mild bike cleaner and a soft brush. Check for any signs of wear or damage, like chips or bent teeth. If you notice any issues, it might be time to replace the chainring. Keep it dry to prevent rusting, especially if you ride in wet conditions.
