Hub. hub is center part a bicycle It consists an axle. and a shell.

The shell typically two machined flanges to spokes can attached. Hub can be with press-in or free or, in case of designs, the may be to a hub shell. axle is to dropouts the fork the frame. axle can using a release – lever and that pass a hollow designed to for installation removal of wheel without tools (found most modern bikes and mountain bikes). – the is threaded protrudes past sides of fork/frame.
