BB7's do not self adjust, but a blind, retarded, turtle could adjust them.

 

^^^^
bb7's are the easiest disc brakes to set up. Plus they are going to have more power but a little less modulation then the hayes strokers and I can't even begin to tell you how many blown master cylinders I've seen on crap hayes disc brakes. The only real disc brakes for mountain bikes are made by avid, formula, and hope. Everything else falls waaayy short.

 

I've got Juicy 5's, I dig 'em.

 

formula's are the isht! the lever action feels like they were made for space shuttles or something. so smooth...
