I'm thinking of buying a rear one, because my current MX1 is just sucking out. Appearently they sandwitch the disc instead of pushing it. Sounds like they should work well, but I'm worried about stength. I really don't want one to break. Does anyone have any experience with them? Would anyone recommend it over an Avid bb7?

They're a lot cheaper.
