Well, I don' know how this will work, but yesterday I moved my Louises to my hardtail.
My HT had some BB7 with 7 inch rotor front, 6" rear. The rotors were, I think, the ones with the holes in them, not the cleansweep.
I removed the hardware of the calipers (adapter and the cps thing), and used to install the magura calipers. It did work, and setting up the calipers was a breeze.
I couldn't remove the rotors from the wheel because one of the bolts was stripped and I could not get the torx wrench to move it. So I'm keeping those rotors and see how it work.
