French bike and stem. Compared to standard bike ISO parts, French stem diameter is smaller by 0.2 mm at the quill (inserts into headset) and smaller by 1.0 mm at the clamp (around handlebar). I can find old French stems no problem, but they won't fit a standard handlebar unless you hog out the clamp. I did that on the AVA, took some time and effort. Next time I will use a standard stem and sand down the quil instead.
