Hehe, looks pretty straight forward but there's a few spacers (or custom made bells) and custom made brackets involved to get it to fit onto the ST170 hubs. There are either just too many compromises made or too much work/expense to fit properly to ST170 hubs IMO.

You can obviously fit them to the RS hub knuckles but they are like rocking horse shit (at least one side is no longer available) and very expensive second hand, they also have a different diameter hole for the strut...There may be other issues too but I don't know of anyone who's attempted it.

The only person I know that's done it says it messes up the brake balance too and overall wasn't worth the effort.
