Hey-
I just got a new bike(to me anyways) and it came with a carbon fork (it's a Profile BSC if it matters), which has a carbon steerer. I have searched and searched and cannot get a straight answer to two of my questions:
1) Why can't I use a star nut? The bike has one of those internal headsets and it came with a cane creek headset and a cane creek star nut+cap, but according to this site(still waiting on profiles reply), I can't use it, but I can't find why not.
2) What if I don't have a torque wrench? How should I go about installing my stem and tightening it without a torque wrench(again, absolutely mandatory according to this site), isn't there any other way?
Thanks alot, and I am sure there will be more questions from me about this soon!

Infact, I have already thought of one, how many spacers can I have under my stem(I seem to recall under 20mm's worth, is this correct?)?, and how about on top of my stem?(can't seem to find whether this matters or not)
Again thanks for any help!!
