    IS Mounts and rotor sizes

    So, I'm looking at my rear IS mounts, currently fitted with adapters for a 203mm rotor, and I'm wondering...

    If I were to fit a smaller rotor, would I have to buy adapters for each of those, too, or are IS mounts built out to fit, like a 160mm rotor without an adapter?

    Questions, questions.

    Most IS rear calipers will fit a160mm rotor without any adapter. What brand/model of brakes do you have?

    They be 2008 XT's. I like them quite a bit - I wasn't originally going to buy them seeing as they're more of a trail brake but an unbeatable deal came up and they haven't wronged me yet.
