Got a new set of forks so new hope headset was needed, these are the official insertion bushes for 1 1/8 hope headsets.

Basically you remove the bearing from the cup, put this in its place and you use it alongside a quality headset press, the hole in the centre of the bush is quite big so really meant for the high end presses like park tools.

If you can’t afford a park tools one then you can press them in with a bench vise or failing that belt them in with a hammer (not really recommended but works as a last resort) as long as you have these bushes in your shiny new hope headset shouldn’t get damaged.
