Does anyone have information or experience about the typical wedge angle for quill stems?
Saint Sheldon doesn't mention a specific angle, but I did find an ISO document of dubious brevity that claims it's supposed to be 36 degrees since 1990. Measuring a stem (early 90s I think) I have with me, I'm getting more like 34 degrees.
