Thank you!

Specialized is mailing me a new headset cover. The representative said the material under the seal was made a tiny bit thicker/ more robust.

Hopefully this fixes the problem. My headset has been solid since adding 0.5mm of headset shims, but the shims create a tiny gap between the frame and headset cover.

Lots of different terms for these parts! To be clear, the problem isn’t the Top Cap. The representative I texted with called the part “cone top cover “ and suggested part number S242500005 from a dealer. This is supposed to be similar to the Tarmac SL6 part but with tighter tolerances. The manual calls it a compression ring.

Correct. I’m expecting something like this, but we’ll see when it arrives.

I received part S242500005 today from specialized. Hope it works!

In fact, I think they have a reputation for being difficult to remove. I've never had to do it, but it's worth thinking about.

I can verify that they're a bear to remove, but they also don't slip

In fact I've replaced a few slipping HS plugs with the SBC version because they don't slip
