Looking at getting some new brakes but can't get a post mount rear caliper in XTR.
I know standard disc size for post mount is 160mm, but will rear IS run 140mm?

Help please

If you fit a specific rear caliper then you run a 160mm rotor. However if you fit an IS front caliper on the rear then you run a 140mm rotor.
