    What adapter do I need when going from 6" to 7" with my HFX-9?

    So yeah... What kind of adapter do I need when I replace the 6" disc to 7" on my HFX-9?
    Hayes' own website doesn't help much...

    Reviving an old thread since I am in a similar situation,
    for some reason I thought I could use a rear 160mm adapter for a 7" front rotor.
    But after one ride I saw that the pads are pressing partly on the rotor arms.
    The fork is a 2002 Rock Shox Psylo SL which has a 9mm Skraxle.
    As a quick fix I shimmed the caliper out a little but I am not sure if I really want to keep that in the long run.

    Thank you
