Using your Sunday Darkwave BMX Frame is easy. First, make sure to install all the necessary components like the fork, wheels, and brakes properly. When riding, the frame's special features like the wave down tube will protect it from dents, but still be careful on rough terrains. As for maintenance, regularly check the integrated seat clamp, chain tensioners, and brake hardware for any signs of wear or looseness. Keep the frame clean by wiping it down after rides, especially if it gets dirty or wet. Store it in a dry place to prevent rusting. If you need to remove the brake hardware or gyro tabs, do it carefully and keep them in a safe place. Also, when adjusting the chain tension, use the internal chain tensioner in the dropouts. Enjoy your rides with this reliable BMX frame!
