I am changing out a quill stem on an older bike for a friend. The current stem diameter is 1 1/8" (28.53mm) and the headset is also 1 1/8". I ordered a new Profile quill stem in a 1 1/8" size. The packaging clearly states it is 1 1/8" diameter stem, yet the actual stem diameter measurement is 1" (25.18mm). I called the company I purchased the stem from, and they told me to just tighten the quill bolt and the slack would be taken up by the tapered end. I did so, but I am seeing 1/16" gap on both sides. This sure doesn't seem logical to me, but I haven't played around with a quill stem for years. Is this really the way it is supposed to fit?
