10Lightweight Germany Handarbeit fur Beinarbeit
Weighs 174g on my kitchen scale
440mm width
31.8" clamp diameter
174g weight
Not an expert on measuring handlebars, but I'm getting approx 146mm drop (center to center) and trouble calc'ing reach (PM if you need that measurement).
Years ago, I bought a gravel bike with these on them and then moved them over to another bike. In buying yet another frame, the new frame came with handlebars and these currently need a home.
Inside the end they are labeled LWHB-02-440.
Happy to answer any questions.
