Step 1: INSTALLING REAR SPROCKET
There are two rear sprocket rubber packers. Cut one of them and only one. Cut only between the drilled holes.
Place the cut one inside of the spokes.
Place the other packer on the outside of the spokes.
Thread the nine bolts through the sprocket and use the half moon backing plates on the inside. Tighten all nine bolts moving across in a star fashion and a little at a time to allow for an even pull down. Once the sprocket is tight spin the wheel and check that the sprocket runs true.
Deviation can be no more than 1.5mm both ways. Any side-to-side excess deviation can be corrected by spinning the wheel and then tightening the sprocket where needed in order to get correct alignment. Make sure bolts are tight. Notice that concavity or indentation of teeth of the rear sprocket is inward towards spokes. This helps keep the chain closer to the inside of the wheel and spokes and allows for better clearance of the rear stays of the bicycle frame.
