aww, all the mixtes I know of have been listed already (except the belleville, but the reviews on that weren't that great). I was obsessed with getting a new one; but later decided I didn't need two of them

I swing my leg through mine, I always did and now I have too with the milk crate on the back. Makes for ungraceful dismounts when I don't think of which bike I'm riding and try to step through my road bike or smack my leg on the milk crate. Anyway.

I don't know about fitting them, but I can advise on is the style. Retro-looking mixtes is where it's at.

I did find this though:

can't say how accurate it is, might be a good place to start.
