I wanted some of those usb's, but they put the cage further from the bike. This is bad for my application because I want to put a bottle under the down tube, and don't want to waste much space. BITD, cages lent themselves to using clamps. Now, that's not so common. I just saw one at the LBS that I think I'm going to try. I'll post the brand later. I already have a vintage cage on my road bike attached with hose clamps. Works fine if your cage has a mount like that.
