[QUOTE=ilovecycling;13334882]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.

Headset stack height - if the headset is considerbly lower when all is said and done, are you OK with the new stem/bar height (not that it would be significant...)
until you are - you could put a spacer above the stem and ride for a while, until cutting.
Starnutz - generally depreciated for carbon steerers, compression nutz being preferred.
actaully I like compression nutz for alu also, since all they do is help position the stem before tightening stem bolts...
starnutz already installed - don;t screw with it... it's in there and as long as it hasn;t badly notched the steerer, you might as well use it for the cap
OR drive it down further, well below where the stem covers the steerer, down by al least an inch below stem.
extract? haven;t seen that successfully done
problem with starnutz is, when the stem bolts are properly tightened they will slightly compress the steerer, the starnut edgesthen can cut into the steerer, hastening failure of the carbon tube...
segway to the Paris-Roubaix clip where Hincapie ends up sitting up with the handlbars in his hands, resulting in eventaul broken collarbone - nasty...
not sayin that his bike had a starnut installed, but the end result might be the same, same...
most races - tough on rider
Paris- Roubaix - hell of the north for both rider and bike...
