    New fork has Post Mount, Juicy 7 bracket from IS

    Hi.
    I'm looking at buying a Fox F32 120 RLC, and it seems they only come in Post mount for brakes.
    I have a 2007 100RLC and it is an IS mount with Avid Juicy 7's.

    If Post mount is the only option for a fox fork on a new frame I am building up, can I mount my existing Juicy 7's to a Post mount using a bracket AND keep the 160mm rotors?

    If so, what is the best / only type of bracket, and does it effect the brakes?

    Appreciate any help.

    The caliper should bolt directly on - no need for an adaptor unless you want to use a different size rotor than 160mm.

    Edit: Could be wrong - may need one with the CPS washer system they use. I run a 185mm rotor in the front w/ avid brakes. My shimanos bolt directly on for a 160mm rotor though.

    No worries...

    All Avid disc brakes are direct mount for a post mount fork and a 160mm rotor. You need to retain the CPS washers of course, but no adapter is required. As noted, if you wanted to go to a larger rotor, then an adapter would be needed.

    Actually the fork's post mount is what determines the size. I think Manitou at one point had post mounts that were direct for 203mm.

    But anyways, as already said, the Avid caliper is 74mm post mount. If you have a 160mm post mount fork, all you need is to sandwich the cps washer stack between the caliper and the mount, and between the caliper and the head of the bolt. It will fit 160mm rotor without an adapter.

    Many Thanks,

    As with all Avid disc brakes since day-one.

    The trouble with common sense is it is no longer common
