Don't have one, won't ever find one my size, like to have one, maybe my wife "needs" one. Any mixte frames made with reynolds/columbus/vitus or the like for the main tubes and forks and stays? There is an 80s SR mixte for sale locally but it has 26" tires(according to the owner). I haven't seen it but I guess it could have 650b's, any mixtes come with 650s?

From wiki;

Mixte

One particular type of step-through frame is called a mixte. In a mixte frame, the top tube of the traditional diamond frame is replaced with a pair of smaller tubes (lateral tubes, or lats) running from the top of the head tube all the way back to the rear axle, connecting at the seat tube on the way. The normal seat stays and chain stays are retained. This provides the lower standover height of a step-through frame bicycle while avoiding some of the additional stresses the step-through frame bicycle places on the seat tube.
A variant on the mixte uses a single, full sized top tube running from the upper head tube to the seat tube, but retains the middle set of stays. [8]
"Mixte" (pronounced [mikst]) is a direct appropriation of the French word meaning "mixed" or "unisex". The usual North American bicycle industry pronunciation of this loan word is /ˈmɪkstiː/.[9]

I recently got a Motobecane Grand Touring mixte for my wife, it has Vitus 888 main tubes, but 2040 fork and stays. It's a nice lightweight, responsive bike, though. The Grand Jubile came with full Vitus 172, but they're scarce as hen's teeth in a mixte frame.
