The hub is the central component of the bicycle wheel. It is mounted on the axle of the wheel and allows it to rotate freely.

In the case of rear wheels, the hub is connected to the sprocket or cassette, which helps transmit the rider's power to the wheels to move the bike forward.
3. Bearing:
The bearings inside the hub allow the wheel to spin smoothly with little friction, improving pedaling efficiency and bike speed.

The spokes of the wheel are attached to the hub, which gives the wheel its structure and strength.Features :
