The VO Mixte is a high quality lugged step-through frame. It is brass brazed from double butted chrome-moly tubing. It makes for a comfortable city bike, but is a light and stiff frame that will also be a pleasure on weekend tours or even club rides.
While mixte frames are traditionally though of as women's frames in the US, in Europe they are often ridden as city bikes by men who value easy mounting and dismounting.
The Mixte has full braze-ons for fenders and racks, including douple drop-out eyelets. There is one bottle cage mount.
It is brass brazed from 4130 double-butted chrome-moly tubing. The wheels are 700c and maximum tire size is 38mm with fenders. It uses extra-long reach caliper brakes. Note that the rear caliper is elegantly mounted on the mid-stay, so there is no awkward cable routing as with many mixte frames. The rear dropouts are horizontal so either internally-geared or derailleur drive trains work perfectly.
Here is what you, or your mechanic, need to know when building up the frame: The headset is 1" threaded (ISO), brakes are extra long reach (55-73mm), BB is standard ISO (or British) with a spindle length to match your choice of crank, 27.2mm seat post, we suggest 45-55mm fenders, 132.5mm rear spacing so both road and MTB hubs fit.
