I test-rode a Norco Cityglide 8 ST before the snow fell and was impressed. It didn't seem to flex at all when I sprinted out of the saddle and didn't weigh quite as much as my Rocky Mountain Metropolis. The only thing I didn't like was the chainguard, which rattled and flexed all over the place. If they had extended it back to the seat stays and fixed in in place there, it would have worked a lot better. The other thing that I wasn't crazy about was the twist-grip shifter. Personal preference, I know, but the rapid-fire shifters seem less cumbersome to use.

E.T.A.: I love the look of that Soma Mixte. I've never had one, but now that I'm old and inflexible, it's starting to seem like a idea.
