Really? It sounds remarkable silly to me. Get rid of pretty minimal drag by increasing mechanical complexity quite a lot? I'll have to wait until I see what the manufacturer thinks of the reliability, but I suspect it won't be much. They'll need to offer a warranty at least as long as Schmidt does, which is five years, to show they're confident they're making a good product.

Now, it's a good *marketing* idea, and most of what VO do are about marketing, so I'm sure they'll manage to sell it. Magical thinking sells lots of bicycle parts.
