requirement on material and jointing is very high.It
is made through the method of jointing and so on.It
mainly consists of rear fork,dust seal,dustproof seal
cover and rear cover of bearing.

down around the vehicle body,there is bearing
shaft or bearing installed at the connection of rear
fork and vehicle body.When rear fork rotates,it will
make rear wheel more flexibly and more stably.
