    Hello, and welcome to MTBR.

    Which Marzocchi fork? PM or IS? Which size rotor do you want to use?

    I don't think that you can fit the Hope IS calipers to Marzocchi post mounts. I know that there were PM to IS adpators which required a 20mm rotor increase, but they do not work with new Marz' PMs.

    I'm sure somebody will correct me if I'm wrong, but I believe you're going to need a new caliper/brake.

    You may have to accept that you can't use the caliper. Unfortunately, I don't know precisely why the adaptor is no good with new ('07 and later) PM, this is just how they are described. I would suggest that you contact Hope directly and ask for an explanation. Even if it would fit, there's no avoiding the necessity to go up to a 20mm larger rotor.

    Here's a link to the Hope adaptor.

    Unless somebody here can clairfy for you, why don't you contact Marzocchi and get their opinion? The fact that both Shimano and Hope specifically state that the adaptor won'y work obviously implies that the Marzocchi post-mounts present some kind of fitment issue.
