DebW - I replaced my bars myself. (and it was very cool and a very fun way to spend a lazy afternoon. the shop checked my work for me afterwards to be sure I did it right and the whole thing was safe.)

The shop is replacing my stem right now, to one with more rise and less reach. (I have a grumpy neck) I'm also getting my headset replaced at the same time.

If it were only the stem, I'd have no issues at all with just replacing that myself. I have a threaded stem, no problem. I agree, retaping/rebriftering the bar is the biggest PITA in that endeavour.

I'm not trying to switch to an adapter and a threadless, I'm going for a Nitto ($40) in polished aluminum to match the other silver (seatpost) on Flossie. I don't know if an adapter and threadless would be more work or not, as I didn't even bother to research it since I knew Nitto made a stem the reach and rise I wanted.
