    get the one that says. "185mm- front" guessing you are going avid as everyone else is 180. So you'll need the Avid front adaptor. you'll also need to get either a post or tab mount depending on your fork.

    doesn't matter, just need to match the adaptor to the rotor size... then get eh adaptor to match. is your fork a tab (screws come in through the side) or stud mount(screws go straight through the caliper and into the fork)?

    ok I feel like a new guy all over

    the mount seems to be Stud mount the screws go through the caliper and into the fork. So if I am getting the G2 clean sweap rotor 185mm what adapter would I need I dont see any listed for 185.

Sorry for so many questions its been awhile since I did any mods to my bike.

    If I read you correctly, you need the 185 post mount adapter.
    And as noted on that page, the hardware IS NOT included, so you'll need to get some bolts.
    I take it that you already have old Avid CPS washers, so you could just go down to a hardware store and buy longer bolts.
    BUT! (no offense), you seem a bit lost, so I'd just get them (bolts) at the same time

    ya.. like Highdell said,.. get the "185 post mount" and for the $4 get the bolts.
    It is strange, as the selection for just that one size in the Pricepoint site say it DOES include the bolts... but I'd call as I believe that's a typo.

    Just to add to the confusion, the Avid post type 185mm front adapter is more of a spacer that you place between your fork and caliper. This is different from all the other adapters where the adapter is first bolted to the fork and then a separate set of bolts is used to hold the caliper to the adapter.

    The bolts on your original setup will likely not be long enough for this arrangement. Make sure you select the "Post 185mm" hardware in the link provided by highdelll.

    Precisely because the 185mm adapter requires a longer set of bolts, these bolts might actually be included as a part of the adapter; so the Pricepoint listing might be accurate. But as thomllama mentioned, best to call them to be certain.

    Clear as mud?
    Go on ahead, I'm gonna take a breather.

    Also when bolting on your adapter/caliper note there is a long and a short bolt(not much difference) if you put the longer bolt where it needs the shorter you might strip the threads on your fork.Just take your time and double check.Also if you are in north san diego I have an extra adapter and bolts you can have for free

    also, with some forks (I think older fox mostly - but it doesn't hurt to mention), you can pierce the fork-leg and the bath-oil will leak out. - Also kind of the reason I steered the OP from just going into a hardware store - sure, if you know EXACTLY what you're lookin' for, you can do it to save a buck or two.
