If you use the expander (top image) in the fork it acts like a star nut. Looks like it then tightens with an allen wrench ((to what torque???)) once inserted into the steerer tube.
Then use the headset top cap/bolt to adjust the headset.
But....
There was another top cap/expander assy included (bottom part of image). It doesn't work with other part and offers very little headset loading (minimal draw down). Looks like it's for use in a alu steerer tube rather than carbon? Is it just one of those bags that gets dropped in every fork box.
Can anyone confirm or correct?
Thanks
