1" cartridge bearings

Hi folks

Hoping someone here can help. I'm after some bearings for my Ultegra headset. Don't have old ones for comparison unfortunately. :facepalm:
Any ideas where I can get some?
Thanks

Mike

Hi
Thanks for your help
I later realized that I had another headset with the same type of bearings in it. Taking one to the local bearing place tomorrow

Its a special Shimano made bearing as far as I know, & no standard replacement is available.

This one?

If so the MTB versions fit too, stx upwards.

If you have the outer diameter of the bearing and can see if my boxes with these in (all now) are the right ones. Never actually checked as never needed to.

Re:

Yes, looks like those FC,

Bearing on table now. Hang on, I'll just nip up to the loft for the vernier calipers!
