Anybody know where the max limit line would be on a GB stem? Or how high I can raise it and still be safe? There are no markings and I have no clue where the threads end on my fork.

I was also thinking of matching it up with a Cinelli XA, that is marked and using that as a guide. Will this work if the quill lengths are similar?
