Avid replacement disc brake pads for Avid Elixir, XX and X0 2 piston calipers. Choose from either Organic or Metal Sintered pad material and Steel or Aluminum back plate.
We have a lot more Avid stuff in the brakes department.
So with all Avid brakes I think squealing rotors are inevitable, but at least they stop you pretty quickly. Loud rotors seem to happen more when it's really dry. Lifespan is moderate - I probably go through two sets per year but I'm always a bit heavy on the brakes.
