These are the part numbers:

And
https://shop.fullspeedahead.com/en/sl-b ... -4-steerer
I have trouble installing them, as they seem little different that the original ones, the inner race is a little sinked on both of them.
They fit into the frame but when installed the upper conical spacer rubs against the outer race and same thing on the lower bearing.
It seams these bearings have the inner race a little sinked in and the compression ring on the upper part/ the crown race on the lower part when tightened doesn’t make pressure on the bearings inner races.
It’s like the compression ring it’s to small on the upper one and the crown race doesn’t fit the lower one.
Any suggestions would be apreciated

Thank you
