    it all depends on the fitting on the fork/frame and the brake.

    so More info needed.

    What brakes have you got ATM? PS, 7 inch rotor sizes are not all uniform, there are 180, 183 and 185 mm rotors. What rotor and caliper will you use and will determine what adapter you should use.

    You've answered your own question haven't you?

    You need a rear IS 180 bracket.

    For XC I don't see the need to go over a 160mm rotor though.
