Threaded headset stems and swapping bars.

I have been thinking recently that it would be nice to have a different set of bars, so I can swap them out whenever I feel like a change, but these quill stems mean we have to remove all the tape and levers.

I was thinking about getting another stem and dedicating each stem to each bar, to make swapping quick and simple. Does anyone else do that too?

Yes.

For one of my bikes, I had a stem with risers, a stem with drops and a stem with bullhorns. One allen key and you're done. Even easier when you're brakeless.

If you got a hinged brake lever, it'd only be two things to undo though, so pretty easy still.

Or get a quill stem with a removable face plate, such as cinelli frog or profile h2o both these have made my life easier.

Yes but the bike I do it with haz a Brakless™ so it's a lot easier.

I have three stems for three different bars (risers, bulhorns and track drops) which I usually change depending on the occasion: risers for the city, bullhorns for long rides... And I must admit that I´m quite fed up of changing them time to time. In fact I´m selling all of them to get some proper compact bars that should be an all-in-one.
