I should have included a picture. It really is better than a thousand words. But I saw ebay auctions where these items are called "pokeless wheels" so I thought that would be an understood expression. My bad, I guess.

So.... is there any disadvantage to using these kinds of wheels? I checked the weight for MTB-type wheels, and these "spokeless wheels" (that's a wrong term, I am becoming evermore aware of this, becuase they do have 3,4, 5 or 6 spokes, but they are cast) are comparable, or even lighter, depending on the material.

So if weight is not, in fact, an issue, it seems that these wheels don't have the slightest disadvantage, right?
