XTR brakes with Avid G3 rotors

I am trying to acquire XTR M975 brakes and was wondering if they would work with the current rotors I have on.

 

I believe that Shimano Brakes use a slightly different sized rotor. Ex. 180mm (Shimano) vs 185mm (Avid)

 

160mm size should be fine between shimano/avid brands. Just make sure you match the brake mount to the caliper.

beast64 is correct. The "7 inch" rotors can be 180mm (shimano), 183mm (hope), 185mm (avid), etc.

I believe the 203mm size is consistent between brands, but I never run them, so I have no personal experience.

 

Also, Avid and Hayes rotors are a bit thicker than Shimano rotors, but it's not a problem or concern.

 

203mm avid g3 front, 160mm avid g2 back. Shimano calipers. Works for me. Shavid!
