That is from the dealer specs (I own a shop that sells Trek) for the 2024 FX 4, which it looks like you have based on the color. I don’t think Trek makes these specs available to retail customers for non-current models but any Trek dealer should be able to pull them up. I think what’s still in your head tube is one part of the bearing cartridge. The whole cartridge really should have been replaced when it was serviced, and I’d take it to the shop and ask them to sort it out.
