As above really, am pondering a present purchase and wondering who, if anyone, has a track record of producing properly lovely light, fast Audax/light touring type frames, but the real challenge is that it has to be a mixte (as in dropped top tube) design.

So, over to the STW Hive Mind. Don't let me down!

i reckon you are needing one of these

14bikeco in London's trendy East London do a ladies frame.

Like this, clicky

All frames are custom made so you should be able to add gears and such like without too much hassle.

That Mercian looks a peach, thanks!

Any more like that?

*Double post edit*

I think these are lovely.
Soma Buena Vista Mixte

probably more hybrid than audax, but ladies and sort of bling

A used frame from Ebay then re-finished might turn out nice.
Early Clauds, Dawes carlton etc.

Strangely I'm on the lookout for one for my missus. Deffo going used and building modern/retro/comfy/fashionable?

whats wrong with your Raleigh?

any of these?

but most of the uk custom builders should be able to sort you out

or get hold of an older mixte and do it up?

miss mercian is v nice though pictures do not show a mixte frame.
