Help with FSA headset collar thing

[Mr. Cow]

Hi all,

Can anyone help me identify a suitable replacement part for that in the below pictures please? It sits on top of my upper headset bearing between the frame and spacers. Its internal bearing (separate to the upper headset bearing) is starting to seize so could do with replacing it. Inside diameter of the hole is 29mm which is about the same as the outside diameter of the steerer tube. Height is 16mm. Have checked on FSA website but I can't work out which one it is

Thanks

you need to work out, by reference back to the manufacturer, what headset product code it is, and then work out what replacement bearing it needs.

If you cant get the exact same height you can always just stick some more spacers to fill the gap , my old boardman has the same style and i replaced it with a generic top cup with an extra spacer

Why not just replace the bearing? They are easy to come by.
Re-use the collar.

I would, but the bearing seems integrated and doesn't come out. The upper headset bearing this collar sits directly ontop of is fine (see pics)

what model fsa headset are you using ?
i have fsa 40 acb and the bearings press into the frame with a ring thatr sits on top to compress the bearings then the same cup sits on top, the part your after does not have any bearings in
