These Rocket Sprocket Mini Sprockets are perfect for asphalt and dirt chassis when you prefer to use small gears. They are designed for a 1 1/4' axle and require a 1/4'x 1/4' keyway slot for use, offering great performance and reliability.

To use these mini sprocket hubs, first make sure your axle is 1 1/4'. Then, fit the sprocket onto the axle using the 1/4'x 1/4' keyway slot. This will ensure a secure connection. When using on asphalt or dirt chassis, keep in mind that small gears can provide better control. As for maintenance, regularly check the sprocket for any signs of wear or damage. If you notice any issues, replace the sprocket promptly. Also, clean the sprocket after each use to keep it in good working condition.
