    Which post mount rear adaptor (Avid)?

    I did some research and still wasn't sure so does anyone on here know which adaptor is required for a rear post mount frame and calliper with Avid CPS washers and a 185mm rotor?

    The Avid 185mm post mount bracket, unless your frame is designed to use a 140mm rear rotor on the frame's post mounts.

    The trouble with common sense is it is no longer common

    Like Shiggy said.. that's the wrong one.... that's an International Standard not a post mount bracket.. follow Shiggy's link to the right one Thou it's a front mount the rear posts are usually set with the attack angle and such to be the same, but honestly I'd contact the frame manufacture to double check before ordering/trying anything.

    Thanks shiggy, I've given that one a go. I was concerned PM rear would need a different size adaptor for the rear like IS does. Page 50-51 of the Avid parts catalogue is quite helpful.
