Bicycle Research cone wrench.
I’ve got a bunch of Bicycle Research cone wrenches and other tools from my days working at Bike-in-Box in Walnut Creek, but this one is different from the others. I think that it came with the Nishiki Olympiad that I got from Don Milberger’s Bicycle Shop in Concord in 1973 at the height of the ten speed craze and the early days of Bicycle Research. In any case, thanks Don for all the tools.
