I use drop bars, flat bars and mustache bars on my Wabi Special fixed gear bike. I have an IRD "locking spacer" that holds the front end together and maintains the headset preload when I remove the bar/stem assembly. The spacer is "loose" until the preload is set, and the stem is tightened. Then, once everything is tightened, the locking spacer is cinched. Everything above the spacer can be removed/swapped out without disturbing the headset preload.
