Mount the chain on the sprocket, and then set the hub
axle into the fork ends.

side of the hub axle. At this time, turn the cassette joint
so that the projecting parts of the non-turn washers fit
into the grooves of the fork ends. If this is done, the
cassette joint can be installed so that it is almost parallel
to the chainstay.
