Odd question for you all. How far up from the bottom should a nitto technomic stem be inserted into the head tube? I picked up a stem at a good deal, but it appears to have been too long for a previous owner who cut it shorter. The angle looks like a good match for the expander, but the top of the angle of the cut is slightly above the minimum insertion line. So how much higher than that should I make my new minimum insertion? Any ideas? I don't have a technomic handy that I can just measure from the bottom to the minimum insertion line (would that be a sensible idea if I did have one?).
