    Shimano XT caliper & 170mm Avid rotor

    1) I'm running Avid Elixir 5 with 170mm rotor on Giant Anthem 29er 2013 and going to buy new Shimano XT BR-M785 brakes. Since they do not come with rotors I want to use the original Avids with the Shim brakes. What adapter/spacer should I use with this combination? Can I use the original CPS adapter? I have that 170 mm in the front.
    2) Rear rotor is 160 mm Avid. Is there any adapter needed for the Shimano caliper and 160 mm Avid rotor or can I mount it directly on the PM frame? Thanks for your help!

    I just got the same bike and put on the xt brakes as well. I was able to use the spacers that came with the Elixirs and it matches up and has worked for me. The rear should just mount to the frame.

    Nice :-) What spacer did you use and how did you mount the caliper?

    My bike came with a spacer that was about 5mm so I put that between the caliper and the post mount on the fork. I believe I used the avid bolts since they were a little longer. I haven't had a problem so far and the pads are lined up on the rotor perfectly..
