    Formula R1 rotors compatible with XT brakes?

    Also, why do they come with adapters? Will my XT disc brake mounts work with it?
    If I need one, which?

    xt compatibility

    Yes they are compatible. The adaptors are used to move the brake caliper out for clearance. I have the r1 rotors with xtr calipers and they work great. The only issue is if you have centerlock hubs you would have to get an adaptor to the standard 6- bolt pattern. These are some nice rotors. Lightweight and have not experienced noisiness with mine.

    Great.
    I'm having some wheels built for me (CK hubs) and need a pair of decent lightweight rotors that perform. I like the Shimano RT76 rotors, but a little heavy.
    Thanks.
