1) Trecking aka butterfly bars. These look very convenient in some ways. Are there any available which bend way out in front for an aerobar position, or with aerobar extensions and resting pads?

2) Extra stem & bar. When I dropped my stem I left a set of spacers worth of length on my steering tube. It just struck me, when I free that space up, I could probably add an extra stem and put a bar in there for mounting things. Has anyone tried this? How did it work for you?
