Having owned a couple of sets of Phaons and a couple of Asgards I thought that I'd be able to make a rare (for me, that is) useful contribution.
However, three of my forks are IS disc and Firmtech mounts and the one that has IS and V brake mounts has M6 threaded studs, so different again....
The Phaon and Asgard sliders are identical though, so maybe an Asgard user has some studs that they could measure for you.
