The ergo bars that came on my Randonee aren't ergonomic for my hands, but I put gel pads under the tape and kept riding them.
The bars that came on my Fuji were damaged a while back, and the bike shop found some that were close to the same shape. They look like the classic round bar shape, and they're a good fit for me.
Either bike can go on a long weekend road ride, depending on how much it looks like rain, and I don't bother to switch bars.
