Hi everyone,

I ordered a new headset for the caad 9 frameset I'm building up and I have a quick question about the star nut currently inside the steerer tube. The headset I'm putting on there has a shorter top cap so the steerer tube will need to be cut down some. The problem is I don't know how to get this one out. It almost looks like there is some kind of glue or possibly a plastic sleeve between the star nut and the inside walls of the steerer tube. I remember my LBS saying something about gluing in a star nut this one time I was there. Is that how these things go in? How do I get this one out if it's glued in?

I also read a warning somewhere online about using this one particular star nut in a carbon steerer tube. It looked just like every other star nut I've seen so I don't know what the deal was with that.

Just looking for some advice here. I'd really appreciate it.
