Sent to the US market, Mixtes seem to be small sizes .. like 5'3" females.
A diamond frame is stronger, and lighter ,
by virtue of less steel needed for the main tube.
Fixed up a Mercian 531 Mixte for a GF, the lighter tubes used let you torque
the head tube with the handlebars without much effort.
