Our common hubs are all in one piece , Infact， there are 3part rim ，hub and spoke .The rim is the part of the wheel that fixes the tire, and the hub is the rotating component that connects the wheel and the axle to bear the load between the tire and the axle. Spokes are the parts that support the rim and hub of the wheel.

The hub has become a functional integral component. It is responsible for carrying the weight of the vehicle , transmission of power, tire heat dissipation and other functions, and as a rotating moving part, the hub has a certain stiffness under the premise of light, fatigue resistance, fit dynamic balance and other conditions.
