Like the Resurrections, they're really not much lighter than a conventional undrilled rim (heavier than a Rhyno Lite). Which makes it all a matter of aesthetics, and whether you actually want to run a "front-specific" rim or not. Personally? No thanks. I know it works for motorcycles and dragsters and stuff, but it's not for me.
Apparently they strengthened the sidewalls by adding extra material there. What, by using the metal they drilled out of the middle? No sir, I don't get it.
Please excuse the short post, not really feeling myself today.
