I found a fixie frame, but it's not a mixte. Still in my basement, untouched. Bullhorns, rusty Raleigh...great potential, though

I'll take a look at the Soma bars. My Jamis is not a mixte, but I want to change the bars on it anyways.

I'll keep my eyes open for a mixte. The guys at Richmond Recycles live in my neighborhood, so I'll ask them, too.
