When I bought my first of those hubs, in 2006, in a pre-built wheel, they were called Dimension hubs. They're different from the Formula hubs in that the cutouts on each side all "point" in the same direction.

I bought one in 2008, and ride that one regularly. The 2006 one lives in my parents' garage and is ridden for a week or so every year when I visit. Both are still very nice.

Strangely enough, both of my hubs have a hollow axle ready for either a track nut or a skewer. So a bit different, in a way.
