Yay, verily on the post with the long list of bar types. I like North Road bars on my classic 3 speed machines.
But, before going to the trouble of replacing bars, it might be well to try on some different bike types. The
rest of the geometry definitely relates. Just the stem, height of bars relative to saddle, etc, might make
a lot of difference without the bother of fitting different bars on the existing bike, too.

All the best,
Don
