Hey Guys,

Just trying to figure what brake setup I'm going to use. I'm wondering if the new Hope rotors that use an aluminium carrier are compatible with XTR calipers?

I've currently got the insanely heavy XT rotors and am wanting to get some lighter ones. I was just going to get some Hayes or Marta rotors and then remembered about these and at approximately 20 grams each lighter Hayes or Marta's and 40grams lighter than XT it would be wonderful if they worked.

Cya, John.

The brake pad of Marta caliper touch small rings which are between aluminium spider and steel brake track of the Hope floating rotor.

The brake track of the Hope floating disc is too narrow for Marta caliper.
