The forks follow conventional design practice with an internal coil spring and damper. Once assembled, this Allen screw passes upwards through the slider to engage with an internal thread in the damper body. For now I’m nipping it up; I’ll tighten it fully once the fork legs are in the yokes – another note for the whiteboard. Don’t miss out the copper washers under the Allen screw heads, or fork oil will leak from the bottom of the sliders
