fabsroman said:I cut all of my forks to allow for 30mm of spacers and then use however many spacers I need above the stem. That way, it allows for some adjustment should you need it. Nothing like cutting a fork with no room left to raise it, and then finding out it was a $700 to $800 mistake when you are uncomfortable with how low the bars are. That is a huge Doh.

Regarding the expander bolt, I just use some common sense. I tighten it with normal force so that it will not slide down the tube, but I do not use gorilla force to tighten it. In other words, I don't get out my biggest/longest wrench and crank down on it. If you want an exact number, I cannot give it to you.
