    Adapter for IS Caliper to PM frame Mount?

    I have an XT M755 4-pot IS caliper and want to mount it on a PM frame mount. The caliper is made for a 160 rotor and I'd like to keep that rotor if possible and not have to go +20 with a 180 rotor.

    Anyone know where I can find this adapter?

    there is no adapter that lets you keep the same size rotor. you'll have to change your rotor to use that caliper

    Was your caliper a front or rear caliper? The IS bolt pattern was usually different for front or rear mount.

    Its a dedicated rear caliper, they're not front - rear interchangeable.

    Anyone know of an adapter, even if I have to upsize +20?

    You might be able to get this to work

    but because it's for a front caliper and 170mm rotor it's hard to say what it might actually give you. If you had a front IS caliper for 160mm rotor and you were mounting on the back of a bike with IS mounts you'd have a 140mm rotor setup. The fact that you have a rear caliper means this may result in a caliper in a position that will run into something or not match any known rotor diameter.
