Re: Adjusting Hagon Mono-shock?
You mention that there is very little damping effect.
The damping adjuster is an allen socket sunk within the lower Aluminium mount. Screw in for more damping & out for less about 1/4 turn at a time.
The only other adjustment is spring preload, this effectively adjusts the ride height of the rear of the bike. Adjust so there is a little sag (from fully extended) with only the weight of the bike & about 1 1/2 to 2 inches of sag with rider/loaded & you'll be somewhere near.
I think that the Hagon shock has a little allen grub screw which needs slackening before adjusting the preload.
