Ehhh, I mean, you can run hic on them, but legacy forks have a shorter forktube to accommodate for an scs. So it might be a little sketchy running hic on such a short fork. But I don't know, I've never tried it. Just usually the forktubes are longer with hic (or ihc) just so the clamp has enough fork to grab onto.
So basically, yea, you probably could. But I personally wouldn't recommend it. But as I said before, I've never tried it so I could be completely wrong haha.
