Thank you for the advice. I have removed the rust and the new cartridge bearing seems to fit ok.
One other thing I was concerned about is further corrosion - but as long as the cartridge and bearing surface are well greased as suggested and kept fairly dry, am I right in thinking this should prevent it getting worse?
(I'm assuming the initial damage was galvanic corrosion as there was a fair bit of rusty liquid in there.)

Hi is the ultegra fd still available? Not sure if @Mr_Nuts took it or not..

I recently purchased a Boardman Pro alu/carbon frame c. 2008 from eBay. Unfortunately, the bottom integrated headset bearings were rusted into the frame. I got them out fairly easily with a cup removal tool and degreased but there's still a fair bit of rust in there. On closer inspection, I also noticed some corrosion around the lip of the headtube too - see photo.
I wondered if anyone had encoutered and/or fixed a similar issue? I was thinking I could remove the rust with some very fine wire wool but wasn't sure what, if anything, I could do about the pitted and worn area?
Thanks
