The color spoke manufacturer introduced that in order to prevent the metal components of the bicycle from rusting, the method of adding a protective layer on the surface of the metal components is mainly adopted.

For example, apply engine oil on chains and gears; bake a layer of paint on the frame and fender; protect the seat springs with a layer of "baked blue" (iron tetroxide protective layer); Electroplating with the spokes of the car (the handlebars and steel rims generally use three-layer electroplating: copper plating at the bottom, nickel plating in the middle, chrome plating on the surface, and zinc plating on the surface of the spokes), and so on.

In addition, the use of stainless steel to make spokes, and the use of aluminum alloy instead of steel to make some components are also common methods to prevent the metal components of the bicycle from rusting.
