It is really hard to say much based on a direct side view of a perfectly flat swept bar, but I think there are a few.
Maybe the Nitto Dove, On One Mary among others... If you are open to a little rise or drop, then you open the door to many others.
There is nothing "mixte" about those bars other than the fact that the picture you show has them on a mixte.
