FWIW, many years ago I came across a document from Mavic which had all
their then current rim profiles diagrammed and dimensioned. No
interior dimensions were listed. Instead they only had: 1)outside
width, 2) width of braking area, and 3) section depth.
I'm not sure this is indicative of the industry; but if it is, any rim
width one comes across is the outside dimension.
BTW, I just opened this document and it's dated 1997.
YAFWIW, I just recalled that Alex had rim section diagrams on their
web site, and they have outside width and inside width (at the bead)
diagrammed. So YMMV.
Okay, so now I'm getting a bit obsessive, but since Peter Chisolm has
been touting Velocity rims here lately I thought I'd check their web
site. A cursory scan finds they have illustrations of their rim
sections, but list NO dimensions. Boo!
