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 .
