Spacers for Profile Designs Threadless Stem Adaptor
What is the maximum numbers of half-cm spacers (or the maximum number of millimeters of spacing) you'd use on the above threadless adaptor? They don't have minimum insertion lines, but I don't want my beautiful '86 Schwinn Pelotons looking like this:
Can we pretty much treat those Profile adaptors like quill stems, or would you only insert it all the way to the hilt?
Here's one of the Pelotons in question, by the way.

Bikes: I never learned to ride a bike. It is my deepest shame.
I have the same adapter and I just use the adapter + ahead-style-stem as a quill stem.
I am confused - are you primarily concerned with the aesthetic issues with having the stem raised up? And are you sure there is no min-insertion line on the quill?
Edit:
I actually have this adapter, not the Profile one. My mistake. I believe the minimum insertion mark is usually 2X or 2-1/2X the quill diameter.

Most stems have a "minimum insertion" mark that shows how high it may safely be set. If you can see this mark, the stem is too high. If your stem doesn't have such a mark, a good rule of thumb is that there should be at least 2 inches/50 mm of stem inside the fork.

Thanks for the tip. I wasn't even aware anyone else made them. (Turns out Origin8 makes them too.)
I don't really mind the lip at all, but I appreciate the tip.
Any idea what the minimum insertion depth (/length) is on these babies?
Any idea which one of these stem adapters is longest? I assume a longer one would afford more flexibility for raising with spacers?

I guess you can discard the part about the spacers--yes, those are for aesthetics. I'm a silly, vain creature, but I freely admit this.
If yours has a min-insertion line on it, how many MM is it from the bottom and how many from the top? Perhaps I can calculate a safe equivalent.
