Note how the internal grooves are different widths. Align the cassette with the hub grooves and assemble as follows. It may take a minute to find the right indexing for the cassette to slide on.

Install the final sprocket similar to previous.

Thread the retaining nut into place as follows.

Torque the cassette retaining nut to 40Nm. It will make a clicking noise as you tighten, because retaining ring has locking notches on it.

Brake disc rotor installation


Remove the disc rotor from it’s packaging and lay it on the hub (align the threaded holes). Note the direction of the arrows on the disc and confirm the orientation is correct.

Review the supplied hardware. There should be six screws (with Loctite already installed) and three securing dog-bone like clips. Note these clips have a proper orientation when installed. You should be able to read the word “TOP” when installed.

Install the clips and screws as follows.

These screws are not hex screws, they are Torx and require a Torx bit to secure.

The six screw are to be tightened in a star like pattern (just like the pattern when you draw a star). The torque value is relatively low (2-4Nm). So take your time tightening in a star pattern and until you reach the final tightness.
