variation in Sun CR18 rims eyelet construction?
So the Sun CR18
is a good basic rim: double-walled, pinned/sleeved construction, brushed sidewalls but not machined, and because of these construction methods it's relatively inexpensive. Comes in a bunch of sizes, for BMX, MTB, road and 27" old-school road - it's one of the few "nice" rims (double-wall, eyelets) still made in the 27" (630mm) size.
Anyway, I just saw that Nashbar had 700c CR18 rims for cheap ($13 last week) and ordered one. Sadly, it doesn't have reinforced. Which will be fine for a front wheel (where I intend to use it, built with an LX hub). But it leads me to wonder about the variation in Sun CR18 rims. The CR18 is pictured multiple times (in different categories) on the sun-ringle.com website but all show the same diagram - double-wall rim with eyelets.
On construction method, should I expect the CR18 without reinforced eyelets to be equivalent to the standard CR18, except with smaller spoke-holes drilled? Or would the CR18 without reinforced eyelets also have a thicker outer wall, to be strong enough to not crack despite not having reinforced eyelets.
It's pretty annoying that Nashbar didn't note that this was an atypical CR18 in their description, although it's not bad b/c I'm only out $13.
