I think this fits within the timeline. I happened across a parts bin DA stem. I've seen them, but never use one. Does the h-bar clamp system use a wedge piece similar to the Cinelli 1/R? Presently this one just has a threaded adjuster bolt, with a separately threaded tip, which looks as if it would just punch a hole in the bar. If so, any known sources?
