I agree with Harvey .
And that's just exactly what I was thinking , about this thread .
>From hanging around bicycle shops in the 1970's , up until today , when I
say "dimpled rim" I'm talking about those dents that the spoke nipples
nestle into .
And for rims with intentionally rough-patterned braking surfaces , I say "knurled rim" or "serrated rim" .
And yes , that pattern really fails to match what a machinist means by the term "knurling" .
And here's your vocabulary word for the day , "reeded edge" . Our U.S.A. dimes , and 25-cent coins , have reeded edges . ( those hundreds of tiny raised parallel ridges all around the edge ) So , the adjustment bolts on a set of Campagnolo Nuovo Gran Sport shift levers , have reeded edges .

> Perhaps I'm confused. I've always used the term "dimple," in connection
with rims, to mean the bulges toward the wheel center that formed the spoke
holes on some Weinmann rims.

braking surface. I've always called that "knurling," although that's really
stretching the machinist's term to fit a stamped surface.
