Early Dia Compe levers
 

I am starting a winter build, and will use some Dia Compe levers I have on a 72 Fuji project. After struggling with much effort, the old solidified gum hoods are off.I I found that the cable stop ends were swaged into the lever body. These are the herringbone style levers. No L or R, just Dia Compe regular stamped on the inside of the lever. No red or gold dots on the pivot shaft ends either.

This made me wonder about the history of these. A set from a 72 Schwinn Continental had some neat cable adjusters swaged in also. These levers generally seem to be ubiquitous, and especially with the various turkey levers and a couple of different styles of brake quick release mechanisms. I guess I don’t know much about these, and lots of other stuff too.

Any history available or timeline? Perhaps considered low end now, but probably at least middling back in the day. The upper level Fuji I am working on specced Dia Compe levers in 72, so they were at least above entry grade.

The basic Dia-Compe drop handlebar brake lever was Known as the Model 144. The same design but with the integral barrel adjuster was known as the model 160. Both models goes back to at least the 1964 collaboration between Yoshigai Kikai Kinzou (Dia-Compe is only the brand name for their products) and Weinmann, when the brand was known Dia-Weinmann. Both models and several variants were still being catalogued at least as late as 1985, so the company certainly got their money out of the tooling. The red pivot pin also goes back at least as far as 1964. Bare pivot pins or those of different colours appear to be customization performed for different clients.
