Northwind was it straightforward changing the top bearing? and where did you get it from?
Hi- pretty easy, it taps out from the inside, there’s notches on either side of the headset “cup” so it taps out with a drift or screwdriver (it’s not so easy to get them out intact, sometimes the inside race comes out first just because of the angles).
The bearing is the same as is used in my Hope 1 1/8th and my Cane Creek S3 and S8- Superstar sell a cheapie

Which actually seem to be pretty decent
Oh, I’ve got a tapered one now which obviously has a different bottom bearing, don’t know about that one yet as it’s only the tops that seem to have the shortened lifespan.
