"In 2013, I had a conversation with Mr. Ooyama, who runs the
last Zunow store. It's located in Chiba, a suburb of
Tokyo. Ooyama partnered with Kageyama in the early 1970s to
cover the northern part of Japan, since Kageyama (and the
Zunow factory) was located in Osaka, southern Japan."
"Ooyama confirmed that Zunow means "genius" and that is the
intended translation... The logo itself went through at
least two permutations: the classic version with a
fleur-de-lis on the bottom, and later, a sort of abstract
geometric version found on the "Hummingbird" series of
Zunow bikes (1965-1970s) were sometimes built with Nervex
lugs... These bikes still have the distinctive Zunow
hummingbird cast into the seat stay tops. By the late 1970s
/ early 1980s, Kageyama was having his own lugs made. Early
versions often had a spade cut-out in the head lugs. Later,
they became more ornate. (There have been) at least three
iterations of the Zunow lugs sets across various bikes and
"...Mr. Kageyama retired from framebuilding in the early
2000's, and took up pottery..."!
