A single eyelet (grommet) serves two valuable purposes: It provides a
better bearing surface for the spoke nipple head, and it helps prevent
galling damage at the drilling from initiating cracks into the rim
extrusion.

Double eyelets (sockets) are still offered by Mavic, Rigida, and Alex
on a few models. Whether they actually transfer any load to the
internal wall of the rim depends on the specifics of the socket and
the rim extrusion and manufacturing tolerances. On modern deep and
semi-deep section rims, sockets offer the benefit of keeping nipples
from going astray within the rim channel while the wheel is being
laced.

The CR18 has eyelets. It does not have sockets
but they are overbuilt with doubled walls that
serve for sockets.

The Sun CR-18 [1] is a good rim, but rather narrow at 22.5 mm.

Are they narrow enough to properly support 25 mm tires? 23 mm?
They still seem a bit fat under my 28 mm tires.

I bought a bike that had a 28-406 Conti GP on a CR-18 rim, but soon
replaced it with a more appropriately sized (for my weight) 44-406
Mitsuboshi Tioga Comp Pool.

No answer to the question of the narrowness of the rim?

Why would anyone want to ride on tires narrower than 28-mm?

I run 35 mm tires on my 700c cr-18's (currently).
