Do those come with washers? That should keep the nipples from pulling through.

I have a pair if Weinmann tubulars that I think are a bit odd. No eylets and the nipple butts up on the inner aluminum wall. There is a wooden spacer between the inner and outer walls that keeps the nipple from pulling through under tension. When you glue up the rims, the glue goes on top of the nipples.

I don't have the most experience, is this typical set-up with rims without eyelets? Or is it something a little different?
