I cant say enough good about them. Came from Avid Elixir CR on my 26" to base model shimano on my 29er. I like the shimanos in every way, and feel they stop better, roll better, scrape on the pad less, etc. The only redeeming benefit for the elexir was that mine (carbon top of the line) let me move the pads in and out against the disc to adjust the throw. But I have to say that if youre looking for MTB disc brakes, I like shimano best!
